Everyone must have his/her reason. But I couldn't think of any reason why I want to stay in the US, not in China. China is exiting, full of opportunity and great food. I am just loving it. (What can US offer? Well, A passport, which can deliver you almost everywhere except middle east. That's about it. ) For Haiguis willing to work in China and not complaining it, the trick is to get the support from the family.
Hillside: am I really the only one here who publically claim to enjoy in China on this board? or you just mis-counting?
