You can ignore the GDP line, it's got a goofy scale (since GDP follows a reasonably stable trend some indicator of rate of change - accelerations and decelerations - would be more useful). But despite the unreliable source I'm linking to, the Budget Deficit line is about right.

Wikipedia also has a nice little article on income redistribution. Honestly, with Wikipedia I don't see why people pay for college nowadays.
