Social Security's operating budget for the 2001 fiscal year (FY) was $7, 223 million. That was the operating budget for the year in which the Bush Administration took office. For the current FY Social Security's operating budget is $9,864 million, which is a 36.6% increase. Of course, you have to allow for inflation. Between October 2000 and July 2008 the inflation rate was 26.4%. This means that there was a net gain in Social Security's operating budget during the Bush Administration after inflation of about 10.2%.
As of September 2000, the closest date to when the Bush Administration took office for which I can find figures, Social Security had 64,521 employees. As of March 2008, the most recent date for which figures are available, Social Security had 60,465 employees, a 6.3% decrease.
The extra money appropriated to Social Security plus the money saved by not replacing employees must have gone to contractors. If that money had not gone to contractors I can make a rough guess that the Social Security Administration would now have about 10,000 to 15,000 more employees than it has and I can say with certainty that Social Security would be giving much better service to the public.
It is all a matter of priorities.
