Why Health Cost Growth Increases after Estimators Say it’s Slowing: Observer Effects and Feedback Loops

“Health cost growth has slowed down, we think. So let’s increase health costs.” This is the federal government’s apparent response to some recent sanguine estimates about the future of health cost growth. We might call this response a policy version of the “observer effect,” where the mere observation of reality changes that reality. In this case, the observation that health care costs may be increasing more slowly than expected creates a political reality in which fewer efforts are exerted to keep costs under control.

Projections based on past historical trends are fraught with danger. The influence of government policy sits near the top of that danger list. Since federal and state spending plus tax subsidies now cover about 60 percent of the health care budget, government legislation decides much of what the nation will pay for health care.  Speaking technically, policy is endogenous to—or influential on—the past trends we measure.

Logically, then, future legislation too has a powerful effect on the direction of health costs. But possible policy changes are an unsteady foundation for cost projections. Government agencies like the Congressional Budget Office try to get around this dilemma by treating policy as exogenous to—or not influencing—cost projections. That way, those agencies can display the implications of current laws, even when those laws imply a growth in cost that is unsustainable.

But health researchers, the public, or elected officials who conclude that past trends will simply continue often fail to account for how policy decisions feed health costs and vice versa. US health care insurance, including that provided or subsidized by government, still offers fairly open-ended access, allowing consumers to spend more and providers to earn more at others’ expense. If policymakers interpret slower cost growth to mean they need fewer new cost-reducing measures and can even rescind some old ones, then as a consequence health costs are going to rise faster.

It now seems clear that Congress and the Obama administration have responded to these new estimates by taking a more lackadaisical attitude toward controlling costs. Two pieces of evidence:

  1. Congress has long squabbled over how to deal with legislation that tried to make the growth in Medicare costs sustainable by cutting payment rates to doctors for certain procedures. Past efforts led to “doc fixes” that held off such cuts for a while and let them accumulate. All was not lost: according to the Committee for a Responsible Federal Budget, these annual forestalling actions involved significant other health cost cuts to pay for each fix. In 2015, however, Congress threw in the towel: it abandoned the old requirements on doctors while providing limited real offsets.
  1. Many Republicans and some Democrats now oppose a tax imposed under Obamacare that requires insurance companies to pay a tax on high-cost insurance plans (plans whose value exceeds $27,500 a year for a family and $10,200 a year for an individual in 2018). Admittedly an imperfect device, the tax did address both conservative and liberal concerns, backed by solid research, that offering a tax subsidy for costs above a cap mainly led to higher health care costs while doing little to expand coverage. Abandoning the high-cost plan tax would effectively increase health costs even more.

Harder to substantiate are cost-controlling initiatives that are abandoned or never undertaken. For instance, President Obama has removed some of the health saving initiatives that used to be in his budget—such as limits on state gaming of Medicaid matching rates—presumably because he thought these initiatives were unlikely to get through Congress, or he had enough health care fights on hand. How much have payment advisory commissions felt that they could let up on new suggestions to reduce prices? In general, how does a perceived reprieve from pressure lead any of these actors to kick the can down the road to their successors or at least until after the next election?  Paul Hughes-Cromwick of the Altarum Institute also asks whether something similar doesn’t go on in the private sector: for example, would specialty drug makers price new entries so aggressively (e.g., Sovaldi for Hepatitis-C or even Jublia for toenail fungus) if we weren’t simultaneously coming off historically low spending growth?

My advice to estimators: include a feedback loop to demonstrate how your estimates affect the behavior of those making decisions on the basis of your estimates. Your projections of lower health cost growth may end up increasing health costs.


A Better Alternative to Taxing Those Without Health Insurance

Although the public debate on health insurance coverage centers on a thumbs-up, thumbs-down fight over the Accountable Care Act (ACA, also called Obamacare), our national system needs a lot of smaller fixes. Many items on this long list of fixes make sense under either a Republican alternative to Obamacare (like the one recently but only partially laid out by Representative Paul Ryan) or Democratic amendments to the existing plan. One example: rethinking the tax penalty on people who do not buy insurance, an issue receiving increased attention as the IRS assesses its first penalties. We can achieve the same end much more effectively by requiring households to purchase health insurance if they want to receive the other government benefits to which they are entitled. No separate tax is required.

The history of the tax penalty

A system of near-universal insurance—where most people of the same age, regardless of their health conditions, can buy insurance at approximately the same price—needs a backup. This need became clear when health reform proposals were first introduced in 2009. Without a backup, individuals have a strong incentive to avoid buying insurance until they are sick, thus effectively getting someone else to pay for their health care. This incentive exists regardless of income level: even a wealthy person who buys health insurance only after becoming sick could hoist his bills on those with lesser incomes who pay for insurance year-round and every year.

The ACA’s partial response to this incentive is to tax those who fail to buy health insurance. The tax for failure in 2014 was either 1 percent of income or $95 per person; it rises to 2.5 percent of income or $695 (adjusted for inflation) after 2015. At the beginning of 2015, millions of people discovered that they owed this tax as they started filing their federal tax returns for 2014.

Practical considerations have always led toward some individual requirement to buy insurance, simply because there are limits on how much government can spend on subsidizing everyone. Our very expensive health care system now entails average health costs per household of about $24,000. The federal government would have to spend just about all its revenues trying to cover all those costs. A mandate to purchase insurance is a partial alternative to ever-more subsidies—as Governor Romney knew when he implemented a related mandate in Massachusetts. At one point, the mandate idea was favored by conservatives even more than liberals as a way to avoid an even more expensive government-controlled system, such as Medicare for all.

What might work better

The problem with the Obamacare tax penalty isn’t the idea; it’s the design. This problem, in various forms, occupied the federal courts needlessly. The central dilemma that pre-occupied an earlier Supreme Court decision was whether government could mandate that we had to buy some particular product (maybe not, it said, but, at least in Chief Justice Roberts’ opinion, it could impose a tax).

Another type of requirement avoids many past and current issues surrounding the Obamacare tax penalty. Simply deny to taxpayers other government benefits if they do not obtain insurance for themselves and their families. There has been no debate over whether government can—indeed,  at some level administratively must—set conditions for determining who receives benefits.

This type of requirement could be implemented in various ways. The personal exemption or the child credit or home mortgage subsidies could be limited; some portion of low interest rates for student loans could be denied. This approach entails no new “tax” for not buying insurance; it simply adds to the conditions for receipt of other government benefits.

Designed well, the denial of any tax benefit could easily be reflected in withholding, so there are fewer end-of-year surprises. Employers, for instance, could adjust withholding for months in which employees did not declare insurance for themselves. As for the many poor receiving benefits like SNAP, most tend to be eligible for Medicaid, so the requirement than they sign up could be handled better by the related administrative offices that deal with them than by the IRS imposing some surprise penalty at the end of the year.

For both administrative and political reasons, this type of requirement can also be made stricter than the current extra tax. The IRS has always had trouble collecting money at the end of the year, and people react more negatively to an additional tax than to a requirement that they shouldn’t shift health costs onto others if they want to receive some other government benefit.

The road ahead

I doubt that any future government, Democratic or Republican, is going to deny people the ability to buy health insurance at a common community rate, even if they are sick or have failed to purchase health insurance previously. The world has already changed too much. Insurance companies have adapted, and so have hospitals. Before health reform, uninsured people could generate partial benefits or coverage by receiving treatment in emergency rooms (where such care is often required by law), and then not paying their bills. With some major exceptions, that practice has declined since the ACA was implemented. No one wants to go back to the old ways.

In a partisan world, of course, a fix of almost any type becomes difficult. Republicans are afraid to fix almost any aspect of Obamacare for fear it would involve a buy-in to the plan’s success; Democrats dread amending Obamacare because it might hint at some degree of failure. Watching the current Supreme Court battle, you sense that many enjoy the fight more than anything else. Still, this simple fix should be added to the list of reforms for consideration when and if we decide we want something better.


Pushing on Air in a Balloon: Health Cost Growth and $1,000 Pills

Numerous recent articles have tried to address whether health cost growth is slowing more permanently. Though I have entered that debate at times , I must admit that it’s a complex question for which there is no definite answer. Policymakers and private practitioners have improved some of the ways that health care is priced and delivered, and more improvements are no doubt forthcoming. But the stories of Gilead and its $1,000-a-pill Hepatitis C drug make one point entirely clear: improving health care costs selectively is like making indentations in a full balloon. Pushing down the air in one place merely makes it pop out somewhere else.

Consider how the government has designed health insurance, particularly Medicare. Essentially, it has delegated its constitutional powers of appropriation to private individuals and companies like Gilead. Congress doesn’t vote to spend more on hepatitis cures. It lets Gilead, along with patients and doctors, make that decision and then shift the costs back to other citizens. As long as Congress refuses to exercise its appropriations responsibility, every cost-saving measure could be nullified by a new Gilead.

The original sin of health insurance, public or private, has been to allow patients to demand and providers to supply more health care while pushing charges onto others. In the extreme, at a zero price to the patient per service received and a potentially unlimited supply of services for which more compensation and profits can be made, it is not surprising that health costs in this country have grown from about 5 percent of GDP in 1960 to around 17 percent today.

Many efforts aim to limit some of our bites of the forbidden apple but not others: fixed payments to accountable care organizations, health maintenance organizations, and preferred provider organizations; bundling of payments; limits on payments for re-admitted patients to hospitals; and so forth. Yet, yet… without absolution from the original sin.

Hospitals and doctors adjust in newer ways not restricted by selective limits. They add extra treatments and service providers. The ability to add on services is often voiced as the problem with fee-for-service medicine, where the quantity of services increases even for those whose prices are regulated or constrained. But there’s more to it than that; adding services is only one way that the air pops out somewhere else. In an industry with significant technological breakthroughs—and make no mistake, Gilead’s hepatitis drug is a major breakthrough—costs can be increased simply by charging a lot more for the new item or shifting services quickly toward areas of high profitability or compensation.

Even where a health improvement might be well worth the cost in one sense, it might still be unreasonable in another. In a typical open-market industry, we might be willing to pay a lot more for any particular good or service than we do, but competition among suppliers helps reduce costs. With the current design of health insurance, competition is fairly limited. My own brief examination of growth industries in the United States shows health is the one sector where above-average growth in the quantity of goods and services sold was accompanied by above-average growth in prices. Think of electronics, or telephones, or other advanced industries as examples of how increasing quantity usually pairs with decreasing prices.

The hepatitis C drug debate often confuses this value proposition in another way. Let’s accept that the $84,000 treatment with Sovaldi—or the newer, perhaps only $63,000 Hepatitis-C treatment with Harvoni (Gilead’s latest offering)—improves patient well-being and even life spans substantially. If the improvements make retirement years happier and longer, rather than being matched by greater productivity and more years of work, then Gilead and its beneficiaries still shift costs onto society, and health costs rise as a share of GDP.

Now, you might ask, what constrains the costs of inventions in non-health industries during those initial years when patents provide a potential monopoly? You and I do. If the cost is too high, many of us simply don’t buy the good or service. The company keeps prices lower to expand market share before competitors come along when the patent runs out. If the government says it will buy the new good or service for us, the limited-demand constraint that we otherwise provide is removed. Government simply cannot promise both that an inventor can charge what he wants for an invention and that the government will buy it for anyone who wants or needs it.

Thus, regardless of the rate at which health costs rise, it will remain unreasonable as long as the original sin of health insurance remains. Without true budget constraints, improvements will be limited because incentives are limited. With government programs, my own view is that every health care subsidy must be put into a budget, with limits raised over time by Congress but in a fair competition with other societal demands, be they education, defense, or currently unsubsidized forms of preventive health care.

Let Democrats use price controls. Let Republicans use vouchers. Let both work on other efficiency improvements that are more likely to be adopted when budgets are constrained. There is no one-time, permanent solution to how best to regulate this rapidly changing industry. With a constrained budget for each government program, however, Gilead would be unable to charge $1,000 a pill, or other health care providers would face a more rapidly declining price for their services, or both.


On the Progressivity of Obamacare

Is the Affordable Care Act progressive in the most effective way?

In a very fine study, Henry Aaron and Gary Burtless at Brookings have looked at the ACA’s potential effects on income inequality and have preliminarily concluded that the ACA redistributes income—largely in the form of health benefits fits—to the poorest one-third of Americans. Most of the law’s additional subsidies—the expansion of Medicaid and subsidies for those buying insurance on the exchange—are highest for those with the lowest incomes. Offsets, such as some new taxes, tend to be concentrated less at those lower income levels.

What the Aaron and Burtless’ study was never intended to assess—and a lingering 21st century concern with almost all government health policies—is the ACA’s effectiveness and efficiency, both for the public in general and those with modest means in particular. For instance, many rewards of our government health policy have traditionally been captured by health industry providers, who are able to charge consumers higher prices. A program can be progressive, but still end up charging the public an additional $2 for $1.50 or $1 worth of care.

The ACA does at times attempt to deal with some of these issues and includes several experiments. But it was mainly directed at improving access, not reducing health costs. Reforms beyond the ACA still are required on that front regardless of which political party accedes to power.


You Can Limit Our Deductibles, but it Won’t Reduce Our Health Care Bills

When the Obama administration recently delayed its mandate on out-of-pocket health costs, experts and politicians started debating whether this delay affects our longer-term ability to implement Obamacare. I don’t think it does, but I also think we’re missing the bigger point. Once again, the United States is facing the total disconnect between our nation’s health care policies (whether Obamacare, Ryancare, or “your favored politician’s name here”-care) and the simple, unavoidable arithmetic of health care costs.

Let’s examine the latest example. Obamacare includes a mandate on insurers that out-of-pocket health care costs cannot exceed $6,350 for an individual or $12,700 for a family, numbers often cited as “catastrophic.” At first glance, these limits may sound high: six or twelve thousand dollars is a sizeable expense. But consider: households spend an average of $23,000 a year on health care. If it is considered catastrophic to ask some households to pay $12,000 in out-of-pocket expenses, then how can—or, more accurately, how do—all households cover costs that average almost twice as much?

A similar mathematical conundrum is playing out in another part of Obamacare. Congress determined that we shouldn’t have to pay more than 9 or 10 percent of our income for a moderately comprehensive health policy in the new health exchanges. But
consider: health costs now average about one-fifth of personal income and one-third
of money income. So how do we cover the difference?

The simple answer is that if we don’t pay in one way, we pay in another. Mandate any new limit on what consumers have to pay directly—on out-of-pocket deductibles, Medicare co-payment rates, drug costs under the Part D legislation pushed by President George W. Bush, or our share of the cost of health insurance in President Obama’s new health care exchanges—and those expenses don’t simply disappear. They just get tacked on somewhere else.

Of course, I’m only talking about averages. So you might object, “Well, at least I’m not the one who pays.” Perhaps true, but not as much as you might think.

Perhaps you are fairly healthy and have lower health needs. Insurance policies, however, shift costs from the unhealthy to the healthy. That’s as it should be, but the cost of insurance adds to any out-of-pocket cost. Moreover, since unhealthy households tend to have lower incomes to start with, and on average probably can’t cover even average costs of $23,000, healthy households probably pay at least that average amount and probably more to cover the income shortfalls from the less healthy. So being healthy doesn’t let us off the hook.

Perhaps you are middle class or even poor. The government’s health policies redistribute costs from those with higher incomes to those with lower incomes, including the retired. We might think that we avoid paying these high health costs by shifting tax burdens to the rich. Unfortunately, government health costs are already so high that the middle class has to share in the burden of paying for them.

More importantly, even if those health costs could be placed entirely on the rich, the rest of us would still pay what are called opportunity costs. When our elected officials require that a tax be spent on health care, they simultaneously decide that it can’t be spent on education or training or highways or other goods and services. The decline in education spending in recent years while health costs continued to rise provides only the latest piece of evidence.

Regardless of cost shifts to the healthy and those with higher incomes, we still pay a lot ourselves, only indirectly. In particular, we pay through lower cash wages when employers purchase health insurance, an important but often ignored aspect of the slow growth in cash compensation for over three decades. We also pay a decent amount through our own taxes, including federal income and Medicare taxes and all those state excise and sales taxes, often on businesses, that get passed onto us in the form of higher prices on what we buy. Finally, we pay a lot by borrowing from China, Japan, oil-exporting countries, and, more recently, the Federal Reserve, and then passing those outstanding balances and interest payments to our children.

And if paying a lot isn’t bad enough, these methods of paying help insure that we don’t always get our money’s worth. There’s fairly clear evidence that for every $100 of costs pushed into indirect and hidden budgets, our costs rise by more than $100 as health care providers find it easier to raise their prices.

So, the next time someone tells you that we can’t afford health costs that are only a fraction of what we actually pay, ask him where he thinks the extra money comes from.


Growth in Income and Health Care Costs

Worried about the stagnation of income among middle-income households? Or about the growth in health care costs? The two are not unrelated. In fact, middle-income families have witnessed far more growth than the change in their cash incomes suggest if we count the better health insurance most receive from employers or government. But is that all good news? Should ever-increasing shares of the income that Americans receive from government in retirement and other transfer payments go directly to hospitals and doctors as opposed to other needs of beneficiaries? Should workers receive ever-smaller shares of compensation in the form of cash?

The stagnation of cash incomes in the middle of the income distribution now goes back over three decades. Consider the period from 1980 to 2011. Cash income per member of a median income household, which includes items like wages and interest and cash payments from government like Social Security, only grew by about $4,300 or 27 percent over that period, when adjusted for inflation. From 2000 to 2010, it was even negative. Yet according to data from the Bureau of Economic Analysis, per capita personal income—our most comprehensive measure of individual income—grew 72 percent from 1980 to 2011.

How do we reconcile these statistics?  By disentangling the many pieces that go into each measure.

Growing income inequality certainly plays a big part in this story: much of the growth in either cash or total personal income was garnered by those with very high incomes. So the growth in average income, no matter how measured, is substantially higher than the growth for a typical or median person who shared much less than proportionately in those gains. But personal income also includes many items that simply don’t show up in the cash income measures. Among them is the provision of noncash government benefits, such as various forms of food assistance.

Health care plays no small role. In fact, real national health care expenditures per person grew by 223 percent or $6,150 from 1980 to 2011, much more than the growth in median cash income. If we assume that the median-income household member got about the average amount of health care and insurance, then we can see how little their increased cash income tells them or us about their higher standard of living.

Getting a bit more technical, there’s a danger of over-counting and under-counting health care costs here. Some of the median or typical person’s additional cash income went to extra health care expenses, so the additional amount he/she had left for all other purposes was even less than $4,300. However, individuals pay only a small share of their health care expenses; the vast majority is covered by government, employer, or other third-party payments. So, roughly speaking, typical or median individuals still got well more than half of their income growth in the form of health benefits.

The implications stretch well beyond middle-class stagnation. Employers face rising pressures to drop insurance so they can provide higher cash wages. For instance, providing a decent health insurance package to a family can be equivalent roughly to a doubling of employer costs for a worker paid minimum wage. The government, in turn, faces a different squeeze: as it allocates ever-larger shares of its social welfare budget for health care, it grants smaller shares to education, wage subsidies, child tax credits, and most other efforts. Additionally, the more expensive the health care the government provides to those who don’t work, the greater the incentives for them to retire earlier or remain unemployed.

In the end, the health care juggernaut leaves us with good news (that our incomes indeed are growing moderately faster than most headlines would have us believe) as well as bad news (that health care remains unmerciful in what it increasingly takes out of our budget).

Cumulative Change in Income & Health Expenditures


Education Presidents And Governors: Ain’t Gonna Happen

In last week’s State of the Union speech, President Obama put great emphasis on expanding early childhood education. He’s not alone in recognizing the vital role of education as the launching pad for 21st century growth. George W. Bush wanted to be known as the “education president,” and so did his father, George H.W. Bush.

Many governors have similar aspirations. Jerry Brown, for instance, has gotten headlines for his efforts to restore the California university system to its former high status. State support for higher education has fallen dramatically there, particularly as a share of the budget and of Californians’ incomes but also in real terms. Brown even supported a tax increase to try to reverse this trend.

While I strongly support these types of effort, right now pro-education governors and the president are fighting a losing battle. Their new initiatives merely slow down their retreat against a health cost juggernaut.

California isn’t much different from many other states. The college bound and their parents witness this declining state support in the form of ever-rising costs and student debt. Less recognized is the fall in academic rankings of the nation’s leading public universities, such as many of the formerly extolled California universities and my own alma mater, the University of Wisconsin–Madison.

State support of education hasn’t just declined at postsecondary schools. In recent years, legislators have assigned K–12 education smaller shares of state budgets as well. During the recession, teachers were laid off and not replaced in many states. Efforts to expand early childhood education have also stalled, although the president’s initiative may give it some temporary momentum.

Federal spending policies only reinforce the longer-term anti-education trend. An annual Urban Institute study on the children’s budget suggests future continual declines in total federal support for education as long as current policies and laws hold up.

Education spending will continue to decline as long as health costs keep rising rapidly and eating up so much of the additional government revenues that accompany economic growth. The figure below, prepared by National Governors Association (NGA) Executive Director Dan Crippen and presented by his deputy, Barry Anderson, at a recent National Academy of Social Insurance conference, tells much of the state story: health costs essentially squeeze out almost everything else.

State education

These rising health costs don’t just place a squeeze on government budgets; they also are one source of the paltry growth in median household cash income over recent decades.

Within states, health costs show up primarily in the Medicaid budget. As the NGA numbers demonstrate, recent federal health reform did little and is expected to do little to control these state costs, despite large, mainly federally financed subsidies for expanding the number of people eligible for benefits.

With populations aging, state and federal governments now also face demographic pressures to increase their health budgets. Large shares of the Medicaid budget go for long-term and similar support for the elderly and the disabled. This budgetary threat also extends to revenues as larger shares of the population retire, earn less, and pay fewer taxes.

The next time someone tells you that we should wait another ten years to control health costs because we’ll be so much smarter and less partisan then, remind him or her that this procrastinating implicitly advocates further zeroing out state and federal spending on education—and the children’s budget more generally. Presidents and governors will never succeed with their education initiatives until they stop the health cost juggernaut in its tracks.


Who Is Insured or Not Insured by Government?

One of the many dilemmas surrounding federal health care policies is that the government only partially insures most people when it subsidizes health care, but we want to pretend that once “insured” we are all entitled to the maximum health care available. This puts a lot of weight on the definition of “insurance” and creates misunderstandings about what the government does and does not do.

This issue came up in a column by Bruce Bartlett, who notes that Republicans may now oppose an individual mandate, but they do support (directly or indirectly) a mandate on hospitals to provide emergency care. Moreover, while ignoring their effective support of this mandate, and the effective taxes necessary to pay for it, Republicans maintain that the emergency-care mandate means that everyone has some amount of insurance coverage, however partial it may be.

This debate raises the question of what it means to be “insured.” No government plan covers everything. For those soon to have access to the exchange subsidy available through Obamacare, the “silver” and “bronze” plans that could be subsidized still cover only some costs. Medicaid, in turn, generally pays providers less than do other insurance plans; as one result, the more highly paid (and, often, more highly skilled) providers are less available. Similarly, Medicare does not cover all health services, including long-term care, and some doctors now refuse new Medicare patients, though that system’s payment rate is still higher than Medicaid’s.

You may argue that you want equal coverage—if some people get Cadillac coverage, everyone should. However, no elected official from either party seems willing to raise the taxes necessary to pay for such an expensive system. The reason is obvious: such health care would absorb all the revenue currently raised by the federal government and then some, leaving nothing for other government functions.

Even then, some people would step outside the system and buy a Mercedes policy, so inequality in health care would remain. Thus, the notion that everyone gets the same health insurance coverage, even in the most nationalized health system, is pure myth. But if people are not going to receive the Cadillac or Mercedes coverage from government that others obtain privately, how should Congress design policy with those multiple gaps in mind?

I don’t think there is any easy answer, but I do think that researchers and analysts should be more precise when reporting on “insurance” coverage. For example, the Congressional Budget Office produces counts of how many people would be insured under various options, but such estimates by themselves are misleading. Insured and not insured for what? For instance, if everyone received a simple (say, $5,000) voucher, with few restrictions other than that it must cover health care, almost everyone would buy at least a $5,000 insurance policy. On the other hand, if government dictated that the voucher had to be used to buy an expensive plan that many people couldn’t afford, then supplying a voucher would not produce fairly universal (yet partial) coverage.

Alternatively, one can’t assume that a highly regulated system will automatically provide whatever care is specified, since what it pays affects which providers participate in the system. The implicit assumption—and I am not judging it here—may be that many providers are so overpaid that cutbacks would have only limited effect on the care provided or the quality of the doctors and nurses who would accept a lower-paying career.

The ideal but difficult approach for researchers and budget offices, I think, is to note as best as possible what coverage is provided by regulation or subsidization of emergency rooms, Medicaid, Medicare, exchanges—indeed, of each government engagement in the health care economy. Note the expected gaps, whether in preventive care, higher-priced doctors, drugs, or other services. Finally, compare the extent to taxpayers and insured individuals avoid coverage gaps by paying higher taxes or more for their insurance.

In any case, a dichotomous count of who is “insured” or “not insured” is too simplistic. Almost any government health insurance policy is partial in care and cost. If Republicans want to claim that emergency room care is a type of insurance, then they should also acknowledge what is not insured through that mechanism and the implicit taxes on those who end up covering the emergency room cost. If Democrats want to claim that vouchers provide less insurance than a more regulated system, then they, too, should specify just what additional insurance they claim will be covered, at what cost to whom. Both parties should also make coverage comparisons for systems that are equally cost constrained.
