We would be mad as hell in Tx if we had to pay Ca debts, and we have no long time nationalist divisions.
We'll probably get to test your theory in the not-too-distant future!
The thing of it is, nationalism is not a "system," but, like capitalism, a phenomenon. It happens naturally, simply because human beings are the way they are.
You don’t think this is already happening through our taxes?
Unfortunately, pork barrel politics has always been the game. California had some big national politicians in the 1930's, and got an infusion of federal money to fund building of two big bridges on SF Bay, among other big projects. Doesn't look like a debt, but it sucked a lot of money from elsewhere. In the 1960's, Phil Burton and brother John Burton sucked more money from Washington. Lately, it's been Pelosi and Feinstein sucking federal money into California, latest project is high-speed rail (including a billion dollar one mile tunnel in SF's Chinatown). So, in a way, Texas and other states are paying some California debts. You just can't easily see it.
