US. Or China if you are Chinese

Both in longer term ofc

China perhaps... but US? really? personally I can't think of any single person who grew up (like me) in Europe and would choose US as a destination.

From my point of view is as awful as it can get: stark inequality, literally hundreds of thousands of homeless people roaming, no basic health care, but to be honest just the number of guns pro capita is enough to keep me and most of other Europeans away for good, it's just insane for what we're accustomed to. And I'm not even referring to the dystopian situation worsened daily by the current administration.

Unless you're the kind of person who confuses absolute numbers (e.g. money you can spend per month) for actual wealth / quality of life / freedoms / rights protection / etc. Then perhaps USA is the right place, I guess?
