I am genuinely curious, as this often comes up in these discussion. Often, an argument would be that moving away from family and friends to a country where you do not speak the language is difficult. And yet, millions of people move to the US, which is a lot more difficult. So why not?
The reverse is also true. There isn't really a huge migration from Sweden or Switzerland to the US.

We live in a society and world where you're brainwashed since your birth into thinking that money is the most important thing in the world. Thus people that already make good money move to the other side of the world (say to Silicon Valley) because they will make much more money there.
Then they find they aren't necessarily living a better life, just that they can afford more things.
I've been in places and cultures where there isn't such an emphasis on money and material things, like in central asia, and I think people there live much happier lives than most of us in high income countries do.
