LL, you have convinced yourself you know all about what teachers do so there is no use arguing with you.
You are convinced there are only 1 or 2 good teachers per school-- maybe that is the case in Texas, I don't know (but I have my doubts)
Prep and grading is work, and does take time no matter what you believe. And most typical work years are about are about 250 days, not 360--so quit your 50% BS.
I don't know your career field, but a $30K salary with a 4 yr degree is far from "extravigant". Video game designers are getting double that to start, and advertising artist are makin 90K working not full time.
Yes, BvBE was not the dept of Ed, but it was representative of a lot of "locally controlled" schools. That was my point.
