" I'd argue that China is even better to live in if you're rich."
? If you're rich in the US, you stay rich as long as you keep your money.
In China, your RMB is worth what the Party says it's worth, and you can be arbitrarily destroyed for political reasons.
Excepting issues like 'cheap labour' - on most other secular issues, America is a better place to be rich, once you're rich. (ie notwithstanding non culturally secular issues like the fact most people generally prefer their home country for obvious reasons)
