Your first sentence very succinctly sums up the paradox of Native education both in AK and the lower 48.  The elders mistakenly assume that the younger generations want to live as they did when the vast majority of the time the younger generations want to walk a different path.  One that honors the past but moves firmly towards the future.  

Isolationism at this point will do nothing but tear a tribe apart.  My tribe saw nearly 3/4 of our people (literally thosands) die in a small handful of decades from a similar division in the 1800's.  It is my hope that the AK tribes can learn from that experience without having to pay as steep of a price as we did.
