It's hard to have much ability to impart good faith when you intentionally exclude the amount of money paid in by blue states. The money the federal government is paying to red states is (...mostly) coming from somewhere.
The article states that no state receives more than its residents and corporations pays in federal taxes. People pay money to the federal government and the government pays back some fraction of the money per state. So any notion that blue states are subsidizing red states is ridiculous. What's happening is that the wealthy blue states pay a lot under our progressive tax system and receive a lot in return on a per capita basis.
