Auerbach et al., The Budget Outlook and Options for Fiscal Policy, 95 Tax Notes 1639, 1648 (2002) (providing Congressional Budget Office (“CBO”) projections based on the January 2002 budget forecast). Recently, the CBO has provided the following “intermediate spending path” forecast for combined Social Security, Medicare, and Medicaid spending as a percentage of gross domestic product (“GDP”): 9% in 2010, 14.3% in 2030, and 17.7% in 2050. See Cong. Budget Office, The Long-Term Budget Outlook 7 (Dec. 2003) [hereinafter Long-Term Budget Outlook]; available at http://www.cbo.gov/ftpdocs/49xx/doc4916/Report.pdf. These figures are roughly consistent.

12 See Jagadeesh Gokhale & Kent Smetters, Fiscal and Generational Imbalances: New Budget Measures for New Budget Priorities 27 tbl.2 (2003) (estimating the fiscal gap at $44 trillion); Shaviro, supra note 1, at 1299 (estimating the fiscal gap at $74 trillion based on the “flow” fiscal gap calculation provided in Auerbach et al., supra note 10). In both cases, expenditures and funding are projected into perpetuity.

Poterba ed., 2002) (estimating that only about one-eighth of projected growth in federal spending is attributable to retirement programs including Social Security).

22 Projected Medicare cost growth is about equally attributable to demographic shifts and to growth in real spending per enrollee, estimated by the Medicare Trustees to outpace per capita GDP growth by one percentage point annually through 2080. See Long-Term Budget Outlook, supra note 10, at 4–5; Gokhale & Smetters, supra note 12, at 23.
Although a relatively small part of the overall story, the Social Security situation better exemplifies the picture painted by Professor Shaviro. According to Gokhale and Smetters, the Social Security fiscal imbalance is attributable entirely to past and current generations. The present value of payroll tax contributions by future generations actually exceeds the present value of their receipts. See Gokhale & Smetters, supra note 12, at 28. Thus, it appears that pay-as-you-go Social Security financing would be sustainable going forward. This also suggests that if the Social Security benefits of current retirees and the baby boomers ultimately are curtailed to some extent, this would not be generationally unfair. Past and current retirees and the baby boomers simply failed to fund the system adequately. Of course, significant benefit reductions could create tremendous hardship and may be politically infeasible, but compared with massive tax increases down the road, benefit cuts would increase generational equity.

52 Social Security and Medicare can be seen as a response to individual myopia. If individuals tend to be unrealistically optimistic about enjoying good health or high investment returns in the future, they may save too little in purely private retirement and retiree insurance programs.

56 My colleague Alan Feld suggested that the biblical story of Joseph and the Pharaoh’s dream would provide a very useful analogy here, and I quite agree. In the Bible, Pharaoh dreams of seven lean cows swallowing seven fat cows and seven lean ears of corn swallowing seven fat ears. See Genesis 41:1–57. Joseph interprets the dream to mean that Egypt will enjoy seven years of plenty followed by seven years of famine, and Pharaoh puts Joseph in charge of grain management. Joseph builds storage facilities and stockpiles grain during the seven years of plenty. As predicted, seven years of famine follow, and Egypt is well prepared. Id. The moral of the story for our purposes is that storing grain is a great solution if you do not have to worry about rats.
