The deficit for FY 2013, which ended on September 30, was $680 billion. To economists, what matter is not the amount of the deficit, but what percentage of GDP it represents. In this case, it’s 4.1% of GDP.
For FY 2009, the deficit was 10.1% of GDP. So the deficit has fallen by more than half.
Right now, our most immediate concern is (or should be, GOP) jobs, not the deficit. Yes, we have longer-term deficit problems, but the most important thing to do now is not to make those future deficits worse by failing to create jobs. To the extent we do that, we generate more tax revenue and we reduce demand for unemployment benefits, Medicaid, and food stamps, so the government automatically gets more and spends less without cutting the safety net or raising taxes.
