Some commentators blame major legislation adopted in 2008-2010 — the stimulus bill and other recovery measures and the financial rescues — for today’s record deficits. Yet those costs pale next to other policies enacted since 2001 that have swollen the deficit. Those other policies may be less conspicuous now, because many were enacted some years ago and they have long since been absorbed into CBO’s and other organizations’ budget projections.
Just two policies dating from the Bush Administration — tax cuts and the wars in Iraq and Afghanistan — accounted for over $500 billion of the deficit in 2009 and will account for $7 trillion in deficits in 2009 through 2019, including the associated debt-service costs.  By 2019, we estimate that these two policies will account for almost half — nearly $10 trillion — of the $20 trillion in debt that will be owed under current policies. (The Medicare prescription drug benefit enacted in 2003 also will substantially increase deficits and debt, but we are unable to quantify these impacts due to data limitations.) These impacts easily dwarf the stimulus and financial rescues, which will account for less than $2 trillion (less than 10 percent) of the debt at that time. Furthermore, unlike those temporary costs, these inherited policies (especially the tax cuts and the drug benefit) do not fade away as the economy recovers.
Without the economic downturn and the fiscal policies of the previous Administration, the budget would be roughly in balance over the next decade. That would have put the nation on a much sounder footing to address the demographic challenges and the cost pressures in health care that darken the long-run fiscal outlook.
