I believe the problem with Alaska Native Corporations and the federal 8 contracts has been that the Corporations hired "outside" managers" who used the program to line their pockets and their "friends" who received subcontracts. With the exception of the larger and more sophisticated Native corporations, the smaller ones have been used and abused. It is so sad to see the shareholders living in poverty when the manager of the 8contracts and their buddies profited so much. 
Why the "corporation" system, which is difficult enough for most Americans to understand was FORCED on the Alaska Natives (except Metlakatla) is a testament to the continued effort of the genocide of Alaska Natives/American Indians. As more young folk return with the education needed to run their own Corps. then and only then will all shareholders benifits. If the Corps. last that long.
