Paying For National Health InsuranceAnd Not Getting It
The threat of steep tax hikes has torpedoed the debate over national health insurance. Yet according to our calculations, the current tax-financed share of health spending is far higher than most people think: 59.8 percent. This figure (which is about fifteen percentage points higher than the official Centers for Medicare and Medicaid Services [CMS] estimate) includes health carerelated tax subsidies and public employees health benefits, neither of which are classified as public expenditures in the CMS accounting framework. U.S. tax-financed health spending is now the highest in the world. Indeed, our tax-financed costs exceed total costs in every nation except Switzerland. But the sub rosa character of much tax-financed health spending in the United States obscures its regressivity. Public spending for care of the poor, elderly, and disabled is hotly debated and intensely scrutinized. But tax subsidies that accrue mostly to the affluent and health benefits for middle-class government workers are mostly below the radar screen. National health insurance would require smaller tax increases than most people imagine and would make governments role in financing care more visible and explicit.
In a political culture characterized by "read my lips/over my dead body," the threat of huge tax increases silences the debate over national health insurance. Never mind that Canadians, Australians, and Western Europeans spend about half what we do on health care, enjoy universal coverage, and are healthier. Their taxes to finance health care are higher; or are they? The Centers for Medicare and Medicaid Services (CMS) pegs the governments share of health spending in the United States at 45.3 percent ($548 billion in 1999).1 This figure reflects an accounting framework based on who wrote the last check in the sequence from individual households to providersa government program or private payer.2 Thus, the CMS classifies health benefits for soldiers as government health expenditures, since government actually writes the checks to pay military hospitals and doctors. In contrast, health benefits for FBI agents are labeled as private health expenditures because a private insurer pays the claims. The CMSs approach abstracts from the fact that premiums collected by private insurers may have originated either in the private sector or in government (for example, under the Federal Employees Health Benefits Program, or FEHBP). What the CMS actuaries call "publicly financed" health care therefore will be less than what would properly be called "tax-financed" health care.
To measure tax-financed health care, one should analyze the flow of funds as it first emerges from the private sector (households/individuals or employers) (Exhibit 1
When government grants Jones a $2,779 tax preference, these funds must be made up from elsewhere, if one makes the reasonable assumption that government wishes to keep its budget in balance. Government could simply reduce its spending on other programs by $2,779; for example, it could cut welfare payments or defense spending. In that case, the people who had hitherto received those government funds would be forced to sacrifice indirectly for Joness health insurance policy. It seems reasonable to call this government-coerced redistribution of economic privilege a form of "tax financing" for part of Joness health care. Alternatively, government might choose to ask all other taxpayers to pay slightly more in taxes to cover the shortfall occasioned by granting Jones a $2,779 tax preference. Here, too, government coercion redistributes income from other taxpayers to Jones, in this case explicitly through taxes. One would have no trouble calling this transfer "tax financing" of part of Joness health care. In either case, 46.3 percent ($2,779/$6,000) of Joness health insurance premium was effectively "tax-financed" through the power of government to make such redistributions. Indeed, the Office of Management and Budget (OMB) publishes its estimate of the federal income tax subsidy to private health spendingunder the rubric "tax expenditure"as part of the federal budget. But the CMS does not include this subsidy in its national health accounts. Below, we calculate total tax-financed health spending, including these tax subsidies as well as government spending for public employees coverage. We reach a surprising conclusion: Our allegedly private health care system is funded mainly by taxes. Indeed, Americans pay the worlds highest taxes to finance health care.
We calculated U.S. public spending and tax subsidies for health care for selected years between 1965 and 1999 by totaling (1) direct government payments for health-related activities (for example, Medicare, Medicaid, veterans and military health care, subsidies to public hospitals, and public health and research programs); (2) government payments for health benefits for public employees; and (3) tax subsidies for the purchase of health insurance and health care. We refer to the total of these three categories as "total tax-financed health expenditures." Direct government payments. We used figures from the CMS Office of the Actuary, for direct government spending for health care programs, research, and so forth.4 Public employees benefit costs. Estimating government spending on private insurance for public employees for the earlier years is straightforward; the CMS (then HCFA) published tabulations of these figures for 19651995.5 However, comparable tabulations are not available for 1999. To compute the 1999 figure, we combined data on federal workers with separate data on state and local government employees. We calculated federal health benefits by multiplying FEHBP enrollment by the federal governments average premium contribution.6 We then added an estimate of state and local government spending for employee health benefits from the Medical Expenditure Panel Survey (MEPS).7 Tax subsidies. Calculating the value of tax subsidies is complex because the government offers several tax preferences to health spending. First, employer-paid health insurance benefits are exempt from income and payroll taxes. In addition, health costs paid with pretax dollars via "flexible spending accounts" are tax-exempt. Finally, individual taxpayers can deduct health care costs that exceed 7.5 percent of their adjusted gross income. Federal income tax subsidies. For years since 1975 we used the OMBs estimates of the federal income tax subsidy to health care.8 Unfortunately, there are no OMB estimates prior to 1975. Hence, for our 1965 and 1970 estimates we adjusted the 1975 OMB figure downward to reflect health costs and tax rates in those years.9 Social Security (SS) payroll tax subsidies. We calculated the value of this subsidy by multiplying total employer spending for health benefits by the SS tax rate for each year (for example, 12.4 percent in 1999).10 Because income above a cap ($72,600 in 1999) is not subject to SS taxes, we assumed that high-income persons do not receive this subsidy and adjusted our estimates downward accordingly.11 Medicare Hospital Insurance (HI) payroll tax subsidies. We calculated the value of this exemption by multiplying total employer spending for health benefits by the HI payroll tax rate for each year (for example, 2.9 percent in 1999).12 For 19701990 we adjusted this figure downward to account for employees with earnings above the HI tax cap, using the same methodology as for SS. There was no income cap on HI taxes in 1995 or 1999. State and local income tax subsidies. We calculated the value of this exemption by multiplying the value of the federal income tax subsidy by the ratio of local and state income tax receipts to federal income tax receipts.13 Adjustment to avoid double counting of payroll and income taxes. We made a small downward adjustmentabout 3.4 percent of total tax subsidies in 1999to avoid double counting of the income and payroll tax subsidies.14 Adjustment to avoid double counting of tax subsidies to government employees. The OMB estimate of health-related tax subsidies includes tax subsidies to government employees. Because we already included the entire government contribution to its employees health benefits as a tax-financed expenditure, we adjusted the OMB estimate (and our calculation of state and local tax subsidies) downward by government employers share of total employer-paid health benefits. We compared U.S. figures for health spending (per capita and as a share of gross domestic product [GDP]) to data for other nations compiled by the Organization for Economic Cooperation and Development (OECD).15 Data for other nations were converted to U.S. dollars using GDP purchasing power parities (PPPs). Where figures for 1999 were not yet available, we used 1998 data.
Study Results
Tax-financed health expenditures totaled $723.8 billion in 1999, $2,604 per capita, or 59.8 percent of total health spending (Exhibit 2
As a share of tax-financed health expenditures, tax subsidies and public employees benefit costs rose, despite the surge in direct federal spending after the passage of Medicare and Medicaid. Conversely, the proportion accounted for by direct spending (what the CMS labels "public-sector health expenditures") fell. In 1999 tax subsidies accounted for 15.1 percent of tax-financed health expenditures, public employee health benefits for 9.1 percent, and direct government health spending for 75.8 percent.
In 1965 U.S. tax-financed health expenditures per capita were well below the total spending levels in most other developed nations (Exhibit 4
Most Americans have private health insurance. Citizens of most other wealthy nations have national health insurance. Hence the perception that those nations health care systems are public while ours is private. But these labels obscure the predominance of private medical practice and hospitals in Canada and most European countries and the dominance of tax-financed health care in the United States. As shown in Exhibit 5 The huge role of the government in financing American health care is obscured by the fact that nearly one-third of these tax dollars meander through private insurers on their way to the patients bedside. What originates as taxes paid by private households ends up as recycled "private" spending in the CMS accounts. Insurance firms not only siphon off overhead and profits in the process, they also inflict huge paperwork burdens and costs on providers. We have detailed these costs in the past. For 1999 we estimate that health administration spending was more than $309 billion.16 At least half of this could have been saved through a shift to national health insurance.17 Disinterested civil servants, and even skeptics, agree that U.S. health care costs need not rise under national health insurance because administrative savings would roughly offset the increased costs of care for todays uninsured and underinsured persons.18 While national health insurance wouldnt cost Americans more, it would mean that taxes would pay a bigger share of health care costs and that private insurance and patients would pay a smaller share. Yet government now spends far more on health careand national health insurance would require a smaller tax increasethan most Americans believe. The step from our current level of tax financing59.8 percentto Canada or Australias 70 percent is less steep than the CMS figures on public spending imply. About $130 billion per yearthe amount of the recent tax cutswould get us from here to there. Regressivity of tax subsidies. The sub rosa character of much tax-financed health spending in the United States veils the regressive pattern of government funding. Highly visible Medicaid spending benefits the poor; obscure but burgeoning tax subsidies benefit the affluent who are most likely to have employer-paid coverage and whose higher marginal tax rates translate into greater tax savings.19 For instance, in 1998 federal tax subsidies alone averaged $2,357 for families with incomes above $100,000 but only $71 for families with incomes below $15,000.20 Impact on households. The complexity of U.S. health care financing also masks its impact on household budgets. In 1999 a family of four with the mean per person expenditures spent $17,432 (4 x $4,358) on health care: $7,016 for premiums (including the private employerpaid portion, net of tax subsidies) and out-of-pocket costs; and $10,416 in health carerelated taxes. Of their taxes, $1,578 funded health-related tax subsidies; $943 paid for health benefits for public employees; and $7,895 paid for Medicare, Medicaid, and so forth. Even many uninsured Americans pay thousands of dollars in taxes for the health care of others. Growth of tax-financed share. The tax-financed share of overall health care spending nearly doubled between 1965 and 1999, jumping after the introduction of Medicare and Medicaid in 1966. Ironically, the ascendancy of market-based health policies in the early 1990s coincided with a second bump in the tax-financed share of health spending. The exuberant growth of for-profit medicine was nourished by generous dollops of tax dollars. The small dip in the tax-financed share in 1999 probably reflects both the booming private economy and an artifact (a discontinuity in the data sources for public employee benefits costs). Government versus private employer purchasing role. The federal government is now the largest purchaser of private coverage in the United States, followed by the State of California.21 Although only 19.4 percent of all civilian workers were public employees in 1999, local, state, and federal governments accounted for 22.5 percent of civilian employer health spending (up from 9.4 percent in 1965).22 While 64 percent of Americans have employment-based coverage, many of these are public employees, receive their principal coverage from Medicare or Medicaid, or purchase coverage through an employer but pay the whole premium themselves; private-sector employers contribute to the principal coverage of only 43.1 percent of Americans.23 But even this figure greatly overstates private employers role in funding care; they rarely pay the entire premium, and their contribution is tax-subsidized. Moreover, government picks up the tab for many of the costliest patientsthe elderly and disabled. Private employers share of health spending in 1999 was at most 19.2 percent, under the extreme assumption that none of the tax subsidies accrue to employers.24 If one assumes the opposite extremethat all of the tax subsidy for employer-paid coverage accrues to employerstheir contribution falls to only 11.0 percent of health spending. Even the higher figure hardly justifies private employers enormous influence on health policy. Comparison with other estimates. Our estimates of tax subsidies in 1999 and 1985 are similar to previous estimates based on different methods.25 We may slightly overstate the SS tax subsidy if higher-income employees receive costlier health benefits than do covered employees with incomes below the SS income cap. Conversely, our estimate may understate state/local income tax subsidies if locales with high income tax rates have higher-than-average employer contributions for coverage. We excluded tax subsidies to not-for-profit hospitals ($6.3 billion in 1995), other health care providers, and pharmaceutical firms, as well as reduced payroll tax revenues due to the flexible spending account exemption.26 Hence, our estimate is probably conservative. However, the value of current tax subsidies provides only a rough estimate of the increased tax collections that would accrue if the tax subsidies were abolished. Were national health insurance to replace private coverage, employees or employers (or both) would gain taxable income, but many would find means to shelter part of this new income from taxes. A variety of other ripple effects would occur. Some insurance employees would lose jobs and income; employers costs to administer coverage would fall; and employees who have been reluctant to change jobs or retire for fear of losing coverage would face fewer constraints. International comparisons. For international comparisons we used 1998 data for nations whose 1999 figures were not yet available. Because health care inflation has been modest in these nations, increased spending between 1998 and 1999 could not greatly affect our findings. The OECD figures for health spending in other nations do not adjust for tax subsidies for private health care spending or for government purchases of supplemental private health insurance for public employees. No comprehensive data are available to quantify these items. However, such uncounted government health spending must be small, since total private insurance expenditures are low.27 In any case, tax-financed health spending in the United States exceeds the total health budgetpublic plus privateof virtually every other nation. Our health care financing system is usually portrayed as largely private. "Public money, private control" is a more apt description.
