Carolc, your statement that your life wouldn't change much if the United States were ceded to Indian nations because you don't own land is very naive. You would suddenly be subject to a whole different set of laws which disenfranchise you. You might even have to go live on a "reservation," and have crappy schools and no social services.

You might think that no-one would mind your rent money, but if all the suddenly Indian-owned businesses were to decide you shouldn't have a job, you'd come to be seen as an undesirable tenant. Your life would change immensely because of this.
