I Eliminated the US Budget Deficit...

...on the NY Times, using their handy calculator:

Budget Puzzle: You Fix the Budget

Projected 2015 Shortfall: $418 Billion -- I came up with $716 Billion. A surplus!
Projected 2030 Shortfall: $1345 Billion -- I found $1584 Billion. Another surplus!

Try it, it's easy...when no politicians are around. ;)
