"No Federal Jurisdiction"
This is being asked as a serious question.
Are you saying that native americans do not receive enough money from their
Alaska Casinos to support their culture?
The government is not trying to preserve any culture, that is the pride and prejudice responsibility of the people. The government might try to preserve history in monument, parks, libraries, etc.
At one time the government openly preserved pervasive perpetual welfare populations, it still does but hides that truth behind different program names.
