Jinchafa, before deciding to completely turn your back on Thailand, I have to say don't do it yet. Not if you're going to be teaching actual English teachers. Thai adults are more mature than what you call "unappreciative" Thailand school kids in your post. If you're teaching adults, you won't run into the common problems that are merely symptoms of a defunct education system. If the pay is upwards of 40,000 Baht and you're provided with free housing and/or meals, I'd say jump on it! The only "problem" is the violence in the south, assuming you'll be going there. Even then, I wouldn't worry about it. Hey--ya gotta die someway, right?
