*estimated
Source: Budget of the United States Government, FY 2005, Historical
        Tables, table 10.1 and 13.1; DI Tax Rate and Maximum Earnings
        from 2004 Annual Report of the Board of Trustees of the OASDI
        Trust Fund, Table VI.A.1, pages 125-126
Note: DI Tax Rate is paid by employer and employee, each; after 2004,
      maximum earnings taxed is based on increases in average wages

Among the points that the above graphs and tables illustrate are the
following:

1) Spending for Old-Age and Survivors Insurance (OAS) generally grew
   faster than the GDP up until 1983.  Since then, it has dropped
   slightly in relation to the GDP (but has continued to outpace
   inflation).

2) Spending for Disability Insurance (DI) generally grew faster than
   the GDP up until 1977, dropped from then until 1990, then resumed
   its faster-than-GDP growth.

3) Despite its recent growth, DI spending is still much lower than OAS
   spending.  In 2003, DI spending was about 17.9% of OAS spending.

4) The second graph shows a close correlation between the growth in OAS
   income as a percent of GDP and the OAS Tax Rate.  Likewise, the third
   graph shows a close correlation between the growth in DI income as a
   percent of GDP and the DI Tax Rate.  This may not be too surprising.
   Assuming that the wage base is growing at about the same rate as the
   GDP, then a constant tax rate should bring in the same percentage of
   GDP.  This implies that the main reason for the rising OAS and DI Tax
   Rates has been to support those programs' above GDP growth.

5) The OAS Trust Fund balance approached zero in 1982.  In 1983, $17.5
   billion was borrowed from other trust funds (it was repaid in 1985 and
   1986), COLAs were deferred for six months, and various other steps
   were taken to shore up the fund.

6) The DI Trust Fund balance approached zero in 1994.  The percentage
   of OASDI taxes allocated to DI was increased to shore up the fund.
