I can agree that some aspects of development may appear negative, but at least with regards to the negative aspects described in the Local Futures documentary (which btw is not something I'd treat as a reliable source - being a linguist trained under Chomsky doesn't make you an economic analyst for example) were already common before globalization came through - drunkards and opioid addicts always existed, the disparity between haves and have-nots always existed, and the traditional local power structures were inherently exclusionary. A lot of these kinds of documentaries tend to look nostalgically to some form of a utopian past, but if you have rose tinted glasses on, you don't see the red flags.

PS - I wouldn't extrapolate this conversation about indigenous communities in Inner Asia with those of the First Nations. There are a bunch of different political, economic, and social dynamics that cause this to be an apples to oranges comparison.
