I live 20 min from the navajo rez, have all my life. The navajo govt is probably the most crooked govt of all the tribes, if they end up with it im sure they will be out of biz in two years.
My observation of what goes on at the local rez is that the abundance of .gov programs and money given to them as reparations for the horrible things that europeans did to them in the past, has now turned a population of people who were once the definition of self-sufficient badasses mostly into a group of lazy, government dependent, diabetic, alcoholics that get away with drug abuse/trafficking, poaching, domestic violence, and waterway pollution that would put anyone else in jail for 100 years. It's a pretty good case study for what's going to happen to the entire U.S. in a few more years of increasing handouts that keep making life easier. The difference is that there won't really be anywhere to get the funding from. Not sure what happens then.
95% chance this Remington thing won't go well, I hope it does, but I'd bet against it.
