Not like Western countries didn't invade Iraq, Afghanistan and Libya to put governments that favor them instead.
The japanese and the chinese is an entirely different story that would take books to cover, it isn't quite relevant as I don't remember the mexicans brutally invading the US of A.
Furthermore medicare and that kind of crap is rapidly becoming better than what's available for free in the US, do remember China comes from much lower and will most likely improve a lot still, while the US is clearly in decline.
So as much as you're correct in pointing out that China has its own issues, they're not the same issues, and some people will rightfully choose China over the USA.
As a modestly rich European, I think my family would be much safer in China than in the US, and overall the Europe is still much better than both.
