It's true that in some case you have to blame yourself instead of blaming other people for the misery you find yourself in. In the case of recruiters and agents and infamous crappy training centers in China, misleading newbies on purpose and making them come to China for teaching without a Z visa, it's an entirely different matter. Likewise, a woman raped by a man is a victim and not the evil-doer who is to be blamed. Since you lack the required credentials (degree, proper teacher training etc.), and since obviously you depend on your wife for an income, you feel desperate and therefore would take any crappy job that you could find. Hence, your unfounded defense of crappy recruiters, agents and training centers in China. That makes you a part of the problems in the ESL industry instead of their solution. Folks like you are the traitors to all those good people around the globe that want to make things in ESL and education better.

Take accepting a job in China without proper investigation, it will not only end disastrously but result in one blaming just about anybody else, including recruiters and agents, anybody else apart from oneself. It's the same with personal relationships, if you are led into them by your balls or feeble expectations they are likely to end badly.
