>> most people in the world don’t and have never lived like Europeans

> Yeah, but, as it turns out with modern migration trends, the revealed preference is that they would want to, given an opportunity. Being European, I would also prefer to live like a European.

The revealed preference is that they want to continue to live the same way, but to do it in European countries as they are nicer places to live.

The problem is that they are nicer places to live because "living like a European" is what produces these nicer places to live.
