Bingo.
The states are stupid. The feds are bankrupt. Any state could become more financially healthy than the feds almost immediately especially if they stick to the rules of small, limited government and free market economics.
Whatever state did that would draw millions who, given the chance, will always vote with their feet for freedom over tyranny.
I think most if not all states constitutions mandate they have a balanced budget. I guess part of that budget includes federal funds.
