Well-intentioned perhaps, but sorry, the entire premise of your argument is simply wrong. Have you actually taught English in China or Korea?

When I ventured to China in 2003, it was after working several years as a university instructor, with years of teaching experience behind me and holding two masters degrees.

It is CHINA that seeks inexperienced "malcontents" (as you refer to them -- talk about sweeping generalizations!) as they are much more easily controlled and intimidated. Experienced, well-trained and well-educated teachers have their own set of standards and therefore often clash with employers/management who have no interest in supporting their efforts in creating real learning environments.

Basic office needs such as a working photocopier, internet connection, etc., are often missing. That might be tolerable except for the fact that in my experience in China (and I worked in LOTS of different schools/organzations) these are also the same places who have no teaching materials to speak of (although promised during the interview) and so they expect for the instructor not only to create all materials/lessons from thin air, but they have the audacity to expect the teacher to surrender these self-created lessons to them -- as THEIR property -- which they will bind and sell to students as a future course text, and of course, offering no percentage/royalties to the teacher that created, tested, and developed them in the first place.

I know all the tricks of the ESL trade in China and Korea, and I reject the notion that the problem lies with the foreigner.

Chinese ESL employers most often seek maliable individuals who are not in China for the primary purpose of teaching -- but for adventure (of many varieties) -- who can be threatened with legal recourse, eviction, etc., if they don't jump through lots of ridiculous and exploitative hoops.

One of the first things I was expected to do when I began teaching at a "respected" university in China (Nanjing University of Science & Technology) was to change the failing grades assigned by the previous foreign teacher to passing ones (because parents were upset) which of course, I refused to do. Needless to say, my time at this "honorable" university was short-lived. I'm sure in time, they found an appropriate "malcontent" to carry out their deeds.

Most experienced, well-trained, self-respecting educators would not sign the average ESL teaching contract usually offered in China.

It is the employer that is perpetuating the inexperienced, "malcontent" problem.
