American Native
Did Native American populations fare better during the 20th Century in Hispanic countries?

Which of these two methods has resulted in the most concrete benefit, affluence, and survival of the peoples of those countries, including those descended from Natives?
depends which Latino country you refer to. In some, Native peoples were (are) quite poorly treated, nd just as likely to face genocidal practices. Certainly Mexico, Brazil and Peru seem to have done better.
bad question; there were more than two approaches.
