A lot of foreign guys end up with girlfriends in these parts of the world. Get stuck here with them and eventually go into marriage and kids, while not learning the language, so they just keep with the teaching job. In EFL world you are not really developing any skills, even the contacts your are obtaining aren't going to take you seriously in a career sense. Of course your students will love you and think you are a cool teacher, but even if you have aspirations, you will be incredibly lucky for them to let you into their world.
The far East, even Russia to a much lesser extent, would be a sort of refuge for people who didn't fit in, for better or for worse. It is actually incredibly easy to just drift your 20s away being an ESL teacher. I did some of this myself in the pursuit of starting up a business. I had a fantastic experience but ESL teaching in itself can be seriously soul destroying.
