Big Daddy - only thing I'd note is that you probably want to denominate by people living in the state. Here's some interesting data
http://247wallst.com/2010/08/31/the-states-where-america-spends-the-most-and-the-least-per-person/4/What you'll see is that on a per capita basis, SC gets a little less on a % basis than we pay in taxes - and CA and TX get a lot less.
Great discussion!
