You misunderstand.  I don't believe folks should depend on their enemies for anything.  But I dislike the double-standard implicit in your post.  Before you can demand that Native folks become completely self-sufficient, it's only fair that you return to them all the territory and natural wealth which white folks took from them.  Give them back Alaska--ALL of it.  After the initial upheavals of transition, and the removal of all the foreign drugs and alcohol, they'll work it out just fine.  They did for thousands of years before the feral Europeans showed up.
