While there is some of what you mention going on my personal experience having lived many years in northern Ontario, had many native friends and acquaintances and seen many different bands (some call them reserves) is that many are successful with their own schools, police forces, businesses, and land rental to outside businesses and cottagers but you never hear about the successful ones cause they got their shit together. Only the disasters make the news. It's not necessarily an isolation issue. It's really a combination of despair in the young (they don't see a clear path to succeed in life while holding on to their identity), a cultural shift between the old holding on to past grievances and the young wanting to move on. And a serious lack of individual accountability from so-called adults. For example, First Nations have an astronomical rate of diabetes. The alcohol abuse stereotype, while not as prevalent as people think, is higher than in the general population. Band councils ban booze on their land but people smuggle it and others look the other way. As a people they are walking a knife's edge trying to live in a modern world while holding on their ancestral ways of self governance and cultural identity. I could write more about this but it would be off topic.
