You ain't getting a qualified CS teacher for $70-80k a year at most after spending $100-200k getting a Bachelors and a Teacher's Credential/Masters. And especially when high schoolers have the option to attend intro programming classes at community colleges that will transfer to 4 year universities.

> online courses for teachers who want to gain the extra 20 units in computer science

My mom's a teacher, and those 20 extra units are a de facto requirement in CA to get to the pay grade above Bachelors alone.

In CA, there is a differing payscale for teachers w/ a Bachelors degree, a Masters degree/20 post bachelor units, and a PhD.
