Fun debt graphs aren't so fun - The Grumpy Economist reviews some recent estimates from the Congressional Budget Office about spending, revenue and debt.  After years of sub-2% growth, the CBO is estimating around 4% growth which will fill the government coffers with tax revenues.

But what happens if economic growth remains low?  Oh, man, you don't want to know.  And you really don't want to know what will happen if interest rates reset to historical levels.  Oof.
