On December 16, 2012, Paul Kurgman writes an op-ed in The New York Times in which he states:
The weakness of the economy has led directly to lower revenues; when G.D.P. falls, the federal tax take falls too, and in fact always falls substantially more in percentage terms. On top of that, revenue is temporarily depressed by tax breaks, notably the payroll tax cut, that have been put in place to support the economy but will be withdrawn as soon as the economy is stronger (or, unfortunately, even before then). If you do the math, it seems likely that full economic recovery would raise revenue by at least $450 billion.
Meanwhile, the depressed economy has also temporarily raised spending, because more people qualify for unemployment insurance and means-tested programs like food stamps and Medicaid. A reasonable estimate is that economic recovery would reduce federal spending on such programs by at least $150 billion.
Putting all this together, it turns out that the trillion-dollar deficit isn’t a sign of unsustainable finances at all. Some of the deficit is in fact sustainable; just about all of the rest would go away if we had an economic recovery.
