Mass immigration has always happened over the millennia. Sometimes peoples are replaced, sometimes they end up mostly merged after a few generations.

I don't think it's something that can be prevented or encouraged, it's too many people trying to improve their lives to control it. Especially in a time when we're making most of the tropics uninhabitable with climate change.

Forcing people to move to another country en masse sounds like the failures wouldn't be caused by a culture clash so much as more fundamental issues around being forced to move to another country.

I believe part of the endgoal is to create a fairly homogenous global culture. If you listen to radio stations across the world, many play the same rotten manufactured pop songs... Hollywood and Google/Wikipedia complete the Coca Colonisation.

What does "forced" mean in this context?
