That may be true but remember those rights are only good on their reservation. If you have ever been to one of the poorer ones, I doubt if you would change places with them. Not all tribes have rich Casinos, matter of fact, only a small percentage of them do and most of them are not getting rich.
Tribal law applies on the reservations (instead of state law). And when federal law and tribal law conflict, you’d be surprised at the judicial rulings that comne down in support of tribal law.
Change places with them? I would, in a heartbeat, just as long as the tribal council held no authority. I know, because I used to work for a company that insured them, and I handled their claims; and a more incompetent and corrupt governing body you have never seen.
