From what I see, the discussion seems to have branched out to include much more than buxiban employment. Nothing at all wrong with this as the OP and others need to understand the whole enchilada, but I clearly see them as separate considerations.
For most people buxiban work is crap.
I've never met a buxiban teacher that loves their job. For me, I absolutely love teaching and I am good at it. I know how to break down the material and present it in ways the students can understand. I know how to make it fun and interesting, and my students love me, even the extremely naughty ones. Unfortunately, teaching is a small part of buxiban life. It's a business. Decision making and management is never based on education and what is best for the student, it's based on economics.
This combined with the insane issues of 'face' and general Chinese culture make it a difficult situation to be in. One example of this I have personally experienced concerns glasses. Many students here, for some reason or another (polluting factories everywhere, contaminated water and food) have eye problems. when I first arrived , I was blown away by the percentage of students who can't see well. Anyway, I of course want to help. I see students that will never do well in school because they simply can't see the board. So naturally I think I am doing a good thing by notifying the parents. I would be very thankful if a teacher told me this information and it helped my son or daughter.
Wrong! For some of these backward parents, this is perceived as a direct attack, and they experience a loss of face. The foreigner is saying there is something wrong with my son or daughter! How dare he!
This illustrates the often difficult situation a buxiban teacher finds themselves in. Sadly, the worthless 'teachers' that don't give a damn, and only care about drinking and screwing the hotties seem to do quite well, they just don't care. If you're a person that actually cares, and wants to help people and educate, then it's always an uphill battle and often frustrating. Doing the right thing will usually get you into trouble in this twilight zone. This is not to say you can't still be happy, but it's good to go into it with your eyes wide open.
Living in Taiwan is another story completely in my opinion and probably best discussed in another thread.
