Interest payments on the debt are reported here.
For the 7 fiscal years from 2006 to 2012, interest payments have totaled $2.898 trillion.
GDP has gone from $13.399 trillion in 2006 to $15.811 trillion annualized in the third quarter of 2012 (using BEA and Federal Reserve z.1 Release figures), up just $2.412 trillion, which means we're still in the hole $486 billion after 7 years.
I don't see the so-called money multiplier working too well here. And for all I know, these interest payments are probably double-counted, so to speak, showing up as GDP, so it's even worse than it looks. It's government spending, isn't it?
