Those are certainly good examples that you brought up. Personally for me it doesn't matter if it's public or private, but the fact is in developing countries good places to work at are scarce, very scarce! China though will stop at nothing to advertise overseas and promote herself as sounding like a 2nd coming of the USA with all of the opportunities that were in American from years ago (and are not available now due to the poor economy). This type of deceptive self promotion pulls many naive, inexperienced individuals into the foray and can cause devastating results with giving teachers a bad experience, some of which may lead to even therapy or at the very least depression for over a longer period of time.
