Cool. Let’s welcome them and also stop bombing their countries with our militaries and restricting their ability to clone our working technology and maybe they’ll stop trying to leave their homes.

EDIT: Point being that open borders has the benefit of forcing us to face the ways in which we are harming other places. The fact that currently many people would leave their homes to come here is a feature not a bug. We’re trying to abuse the rest of the world for our benefit and that makes other people unhappy. We should stop.
