The US Budget Deficit Is Primarily Related To Slow Economic Growth

The GOP campaign claims that the US budget deficit is caused by out of control federal spending.  Krugman uses CBO data to show that the difference between projected tax revenues and projected spending is primarily the result of the slow recovery.  Tax revenue is well below projected revenue because of slow growth and mandatory spending on things like unemployment insurance etc. is well about the projection because of the slow recovery.  These factors, related to slow growth, account for 90% of the difference in the projected deficit.  Out of control federal spending is not the problem.  Slow economic growth is the problem.
