20K Chinese H1B Visas are a drop in the bucket in terms of opportunity. H1Bs are for people looking to make modest living, the real money is back in China. Common thing you hear from many nouveau riche Chinese is how poor the west are, young professional couple pulling 300K household income can barely afford to live nicely after inflation. Of course, that's still a very comfortable life, but western upper middle class is not aspirationally "rich" by Chinese standards anymore.
