The Government Accountability Office (GAO) has released the latest version of their "The Nation's Long-Term Fiscal Outlook" report today. As with previous reports, GAO finds little change in the long-term outlook and warns that current fiscal policies are unsustainable (duh!). Despite re-stating the important fact that current policies are unsustainable, the report also helps to distinguish what is driving long-term imbalances. Instead of lumping Social Security and Medicare together and labeling the problem as an "entitlement" one, the GAO report highlights health care costs generally as the major obstacle. The relevant paragraph from the report states: Although Social Security is a major part of the fiscal challenge, it is far from our biggest challenge. Spending on the major federal health programs (i.e., Medicare and Medicaid) represents a much larger and faster growing problem. In fact, the federal government's obligations for Medicare Part D alone exceed the unfunded obligations for Social Security. Over the past several decades, health care spending on average has grown much faster than the economy, absorbing increasing shares of the Nation's resources, and this rapid growth is projected to continue. For this reason and others, rising health care costs pose a fiscal challenge not just to the federal budget but to American business and our society as a whole. Under the leadership of Comptroller General David Walker, the GAO continues to bring an important and under appreciated voice to long-term fiscal policy debates. The short report is worth a read: GAO: The Nation's Long-Term Fiscal Outlook
