Conversation so far:
What is the ANSCA?
In 1971 the United States Congress passed the Alaska Native Claims Settlement Act (ANCSA)
What did the ANSCA do?
The Alaska Native Claims Settlement Act (ANCSA) settled land and financial claims for lands and resources which the Alaska Natives had lost to European Americans.
Did the ANSCA do anything else for the Natives besides settle land and financial claims for lands and resources which the peoples had lost to European Americans.?
The Alaska Native Claims Settlement Act (ANCSA) provided for the establishment of 13 Alaska Native Regional Corporations to administer those claims.

Question: Were their lives better after this?
Self-contained rewrite: Were the Alaska Natives' lives better after the Alaska Native Claims Settlement Act (ANCSA) was passed by the United States Congress in 1971?
