Coming from a Latin American the idea of re-starting your life across the country for college and then again for work (multiple times sometimes) while away from family and friends is very foreign. A lot of the conversation around modern American youth feeling isolated, lacking socialization and not building strong relationships seems that stem from this drive. Another thing that’s really weird and related is another…
From an American's perspective, given how much Latin American migrant inflow we have, it'd be easy for us to say the same about Latin American cultures and not imagining how we could leave everything behind. Perhaps people's choices don't always reflect their desires and instead reflect the economic realities around them. "Getting out" is viewed as success where I was from because "staying behind" meant a worse life…
If you'd wish to make that claim then you'd be awfully wrong.
To start off, you'd be basing your personal opinion on what would most charitably be described as survivorship bias. I mean, try to think about it. The observable sample you're trying to generalize is a tiny subset of a whole population which is the output of a social process subjected to a long sequence of socioeconomical filters.
It would make as much sense as to claim that the average American is excellent at American football by using NFL teams as your sample of the US population.
