By kicking out qualified or even semi-qualified foreigners, they will instead only get ex army types with no brains and degree, who just want to come to china to have fun with the local girls

That's what is already occurring here. As far as university vacancies are concerned, it is clear that only the very top universities can select real teachers with masters degrees from their applicants. The run-of-the-mill universities in China, of which there are many, have no option but to continue to employ first degree holders at best.
Most universities won't get the kind of foreign teachers that they want, and that's only to be expected given the detrimental effect on teacher recruitment of the recent harsh visa regulations introduced by the Chinese government, whose misconceptions re foreign teacher recruitment are indeed laughable in the extreme!
