ELI5: Why do Indian reservations still exist?
gpt
Well, why not? People still support the idea. Although conditions on many reservations are bad, most tribes are much happier with the land than without. It's a place where the members of the tribe can be concentrated, and where they can practice tribal law. There's no real substitute for a people to having their own land.

When people criticize the practice of forming reservations, they're not criticizing the fact the tribes got land grants from the federal government, but rather that they were encouraged or forced off the land they already had.
