41 In 1975, 24.9 million Americans were enrolled in a Medicare program; by 2004, that number had increased to 41.7 million. Ctrs. for Medicare & Medicaid Servs., 2003 Data Compendium: Medicare Enrollees, Selected Years (Nov. 2003), available at http://www.
cms.hhs.gov/researchers/pubs/datacompendium/2003/03pg30.pdf (last modified Aug. 25, 2004). Medicare benefit payments grew from $3.2 billion in 1967 to $252.6 billion in 2002. See Ctrs. for Medicare & Medicaid Servs., 2003 Data Compendium: Administrative/

Similarly, benefit payments for Medicare Part D are projected to increase by 9.7% annually from 2006 to 2013, and Part D outlays are estimated to grow from 0.7% of gross domestic product (“GDP”) in 2006 to 3.4% in 2078. 2004 Medicare Trustees Report, supra note 5, at 2.

44 An example is Congress’s decision in 1997 to shift certain home health agency care from Part A to Part B of Medicare. Because of differences between the Part A and Part B trust funds, this shift “permit[ted] the government to pretend that Medicare’s financing had improved by the entire amount shifted.” Daniel Shaviro, Who Should Pay for Medicare? 13 (2004).

53 Kotlikoff, supra note 49, at 28.
54 Cf. Gokhale & Smetters, supra note 45, at 11. Jagadeesh Gokhale and Kent Smetters propose using a measure of “generational imbalance,” which they define as the present value of remaining outlays to current generations minus the present value of remaining taxes to be paid by current generations (along with government assets). They state that, although generational imbalance can be computed for programs such as Social Security and Medicare, that provide cash to or on behalf of specific beneficiaries, it cannot be computed for government policy as a whole because “the benefits of outlays (such as spending on national defense or public infrastructure) cannot easily be allocated to different generations. . . . Only the revenue side of the rest-of-government’s budget may be so attributed.” Id. at 13. This strikes me as a bit over-scrupulous. So long as we understand the limitations to what we are doing, there is nothing wrong with a purely fiscal measure that overlooks the value of in-kind benefits.

Using President Bush’s 2003 budget as the baseline for future policy, Jagadeesh Gokhale and Kent Smetters estimated in 2002 that the total fiscal gap as of 2004 would be “only” $46.9 trillion.

113 Examples of cuts to Social Security and Medicare that might be politically feasible at some point include raising eligibility ages, not fully indexing Social Security benefits to inflation, and squeezing healthcare providers on their Medicare reimbursements even if this causes many of them to drop out of the program.
114 See 2004 Medicare Trustees Report, supra note 5, at 3, tbl.I.C1 (stating that total Medicare expenditures at the end of 2002 were $280.8 billion); 2004 OASDI Trustees Report, supra note 43, at 4 tbl.II.B1 (providing that total Social Security expenditures in 2003 were $479.1 billion).

116 In addition, because one does not earn additional Medicare benefits at the margin by working more (once one has become eligible, as nearly everyone who reaches retirement age does), the taxes that pay for the benefits would deter work at the margin even if people correctly understood the entire program.

A recent New York Times Magazine profile of Stephen Moore notes, “As Moore readily admits, spending has multiplied like a virus in Washington under Bush and the Republican Congress, but while the club gleefully goes after . . . moderates on taxes, it has yet to take aim at a single conservative for going soft on spending.” Matt Bai, Fight Club, N.Y.

Due to concerns about budget deficits and Social Security savings, however, Congress passed tax increases in 1982, 1983, and 1984, all of which President Reagan signed into law. Id. at 157. The most significant of these was the Tax Equity and Fiscal Responsibility Act of 1982 (“TEFRA”), which was intended to raise $98.3 billion over three years and regain 25% of the 1981 tax benefits.
