It would make no sense for American Indians to leave their reservations. American Indians get plenty of benefits for being on reservations. American Indians get tax breaks, avoid certain restrictive laws and have a lot of leeway on what they get to do. American Indians are also able to leave if they want to.
My opinion does not support segregation in any way, but I do believe they have more benefits by residing on reservations. It is to my knowledge that certain reservations are exempt from certain federal regulations; granting tax breaks, and other benefits for their residents. I believe after all of the damage our federal government has done to the Native American populations, they deserve as many benefits as we can afford.
