Agree completely, from my experience the ratio of Native Americans considered as good people is the same as for any other group of people. Having a backup of the reservation life-style does them no favors. From my experience they are often thought of as uppity if they leave the reservation and become successful. No incentive to improve and even looked down upon if they do.
You hit the nail on the head right there with that statement. My life long besty is an American Indian from the Turtle MTN chipewa, his dad left the reservation with a lot of others in the early 70's when the power plants were under construction, my friends dad stayed behind and got a lifelong job at one of the plants he helped construct and retired from it. My friend went to college for the same and has worked in the energy industry since too. We have had numerous talks about this, he has disowned all of his relatives on the reservation for the exact reason you stated above that I highlighted. He has no time or interest in listening to their bitches and complaints as they all have / had the same opportunities as he and his dad did. They all choose to stay there and be lazy and poor and complain about life.
