Yes, I have, although my experience is mostly limited to Beijing with a bit of time spent elsewhere. Housing is at least as expensive (relative to wages) as it is in a typical western city, despite there being graveyards of unfinished apartment blocks everywhere just outside the 5th ring road. This isn't getting into the brutal working hours and mediocre wages, lack of free healthcare, etc etc. It isn't really any better than the US (not that the US are good, they're just bad in somewhat different ways)
