http://www.cbpp.org/9-12-08bud.htmHOW PROJECTED SURPLUSES BECAME DEFICITS:
Main Causes Were Tax Cuts and Higher Security SpendingThe federal budget is projected to run a $546 billion deficit in 2009, compared with the $710 billion surplus that budget experts projected for 2009 back when President Bush took office nearly eight years ago. This $1.3 trillion deterioration in the nation’s fiscal finances for 2009 can be seen by comparing estimates that the Congressional Budget Office (CBO) released this week with those that CBO released in January 2001.
The story is much the same for the entire ten-year period covered by CBO’s 2001 projection. In January 2001, CBO projected a cumulative $5.6 trillion surplus for 2002-2011. Now, CBO’s new report suggests the nation will amass a cumulative deficit of $3.8 trillion over that same period, marking a $9.4 trillion deterioration.
----------
The dominant factor in the unprecedented fiscal deterioration thus was not the performance of the economy. Nor was it increases in domestic programs. The key factors have been large tax cuts and increases in security-related programs. For fiscal 2009, some $1 trillion of the $1.3 trillion deterioration in the nation’s fiscal finances stems from policy actions, and tax cuts account for 42 percent of this $1 trillion deterioration. Increases in military and other security programs account for another 40 percent of the deterioration. The story is much the same for the ten-year period as a whole. For the 2002-2011 period, tax cuts and increases in security programs account for more than four-fifths of the fiscal deterioration caused by policy actions. Increases in domestic programs played a much more modest role.
