I have recently applied in Europe, U.S., and China for a relatively advanced computer scientist position. The China employer gives me an offer immediately, with almost the same salary as Europe and U.S. in Beijing. Plus the China position promised me a clear path of promotion, which is not in the case for my Europe and U.S. offers.

My current position in Europe is in a famously well-paying institution, but my salary is only minorly higher than China, not to mention all the crap I need to go through moving to Europe.

The Chinese government is investing a crap ton of money and resource into computing, I cannot imagine many other people will make the choice I did, especially when they spent most of their lives in China.
