Having only been to a few remote Alaskan communities, and never for more than a couple of weeks at a time, I'm not prepared to dispute your claims.  However, I have seen similar situations in American (and Western) Samoa, where some Mata'i and despotic church leaders wield power which enables them to grievously abuse and exploit their own folks.  The ruling elite of the "Congregational Christian Church of American Samoa" being among the worst.  In Western Samoa they've burned down churches of other denominations and drove their congregants from the island.

On a global scale such individuals used to be called "neocolonial administrators"--i.e., locals who could be bribed and/or hired to keep the "natives" in line.  Diem, Saddam, Pah'lavi, Noriega, Mubarak and Marcos were among the more prominent examples.  Some "slipped their leashes", some were driven out by their own people, and some were betrayed by their imperialist "benefactors" when it became convenient and/or profitable.
