I think part of the problem here is just a matter of supply and demand.

The demand for native speakers in China is HUGE but how many people with a Doctorate in English would be willing to work in China? Sure, there are some but not many....Sometimes, I think it's just a case of China being happy to get what they can and sometimes the only people applying for work at many schools are people with no College education or experience but that doesn't necessarily mean they can't be a good teacher.

I think that there should be some kind of minimum requirement like a bachelor's degree and/or TEFL but most 'qualified' teachers in western countries would rather remain in their country and teach students who actually want to learn and not just be entertained.

I apologize in advance for any spelling/grammar errors.
