Ive lived or worked on a poor reserve for 23 years of my life. I served in some really ghetto areas on my mission in Texas but wouldn't consider myself an expert on those places. Just like Ive been to New York plenty of times but don't know the first thing about regular life in New York.
I also assure you that my Reservation does not have a hotel or a casino, so I don't have any experience with those wealthy reservations.
