>>512562837 (OP)It's people from the middle of fucking nowhere generally.
Anyone with ambition or grit likely wants to live where they have more opportunities, where there's commerce, entertainment, interesting people etc. That means moving towards cities, especially larger more international ones.
The people who just stay put are usually unambitious risk averse people. Especially so when the place they live is shitty and they still just stay there.
For example, anyone from rural northern states whose family goes back more than one generation is likely one of these losers. Prior to modern climate control and internet, there was no reason to live way up north unless you were born there and are too stupid and unambitious to get out.
Same goes for people who live in the middle of the dessert in Afghanistan or literally anywhere in Africa.
