If each person would be better off if there were fewer people, then you're looking at a zero sum game.

If some groups have outsized resources to play that game, it wouldn't be surprising if they found themselves playing it. There doesn't have to be any conspiracy. Unless they take steps to interrupt the process, people's behavior naturally aligns with whatever is best for the group they feel they're part of.

It's how we got racism and lots of other toxic garbage. To pretend it doesn't exist is to give it a place to hide.
