The amount of cash they are getting is irrelevant to the previous conversation. A NAP was broken, and we are paying.
Now! In my neck of the woods the Indian Reservations are doing pretty dern well.
Indian Res in Washington by the large part are flexing thier muscles. They run no tax tobacco stores, no tax alchohol (which is 50% cheaper than normal stores because of the State sin tax).
In some areas, "traditional" indian land is being given back and ANYTHING that is on it is being torn down or outright given to them.
Then we have the casino's! The indians are doing VERY well on these. Entire tribes are being paid out via a bankroll checks monthy and they still collect the federal money.
In fact it is a VERY big deal in my area if you can claim even a 10% indian as you can tie yourself to a tribe with a casino and start collecting a check from the casino.
