>In CA, there is a differing payscale for teachers w/ a Bachelors degree, a Masters degree/20 post bachelor units, and a PhD.
It's this way in other states as well. I briefly looked into teaching and the pay range was $30-45k because I only had a bachelors. My 10+ years of experience meant nothing. If someone was teaching any other subject fresh from college with a PhD it'd be closer to 60k-70k.
Years of teaching didn't mean much either. It was basically cost of living pay raises unless I went back to school and got a masters/phd.
