neither, if I would be non-european, I would choose either europe or australia. better quality of life, more personal freedom (yes, compared to US, the land of free), and just a more interesting places to be (EU culture diversity is still astonishing to me even though I live here 34 years already, Australia has all south east asia and great barrier reef just next to it, which are amazing places to explore)

But that's because you are not looking to immigrate. But there are countless of others. And Europe is heterogenous and not very welcoming .

> If you are a "skilled" person of foreign nationality would you rather go to the US or China if you would have an option ?

Do you know if China is evolving culturally? The reason I wouldn't want to live in a place like China or Russia is that people there are not socially developed. By that I mean, people there are not pleasant and rudeness is the norm. Hopefully, China will be different in a decade or so.

Hard to say. They are experiencing "got rich quickly" syndrome of post-communist countries.I doubt China will be different anytime soon (that includes your decade :-)) as it is an isolated world within a world.
