Not knowing you, or where you come from I will take your comments at face value. But one also has to criticize the schools who knowingly just hire white faces over the qualified to teach in China and then pay them bottom of the barrel salaries. So it is a two way street here. You have, somewhat, alluded that both sides need improvement.
As has been my argument with many local teachers in China, if we foreigners are not qualified and a drain on the education system in China, why do you bring us here? The schools are the ones who advertise for foreigners and do all the paperwork for them to come here. No one is telling the schools you need to bring this foreigner and pay them this amount of money. The accountant has a fit at my school every time she gives me my paltry 5,800 yuan salary every month and then goes on to complain that she earns half. She does not take into consideration that I am alone here, prepare all the classes myself, and try to be the best teacher I can. Pretty much, you get what you pay for. If this school paid me less than what they pay me now I would not be here. If a foreign teacher would be paid what the school accountant got paid, imagine what they would get. If my school would pay a foreign teacher twice my salary, again imagine what they would get as well. I am not the best teacher, or the worst, but damn it I try. I came to China with 4 years of ESL experience at the high school and middle school levels in the USA so I am not a green horn here. By the way, I don't smoke, drink, or chase skirts and it still irks me to be thrown in with the lot of foreigners you have described.
