And even if you were 100% driven to teach, you could be consulting for a code school or something else thats far more lucrative. I'd consider at this point the only people who are actually teaching full time would be people doing it for charity. Except, instead of being thanked you have to navigate all the administration and just plain pains in the ass that come from being a teacher.

The most likely people to go teach how to code are:

1) People who are only academic and don't have any desire to join the private sector (unlikely to be the best teachers)

2) People who've joined the private sector and have their retirement already done (unlikely to put up with administration)

3) People who code as a hobby, have a spouse or other financial support (hard to find at all)
