Uhhh... I beg to differ here. Ever so many of my off reservation Indian (I can use that term - I am one!) immediate family members, other relatives, all members of the Colville, Spokane and Coeur d'Alene tribes pay all the same taxes you do.
My on Rez relatives may not pay state taxes and that is right as the Rez is not part of the state but is a nation unto itself.
Please, don't even get me started on this issue until after 2 Nov... for now, I've got a President to re-elect, and a congressman or two as well...
p.s. there is nothing that white America fears so much as a rich Indian.
