Hope springs eternal.
I don't know where the non-leftist indoctrinated teachers are going to come from. 3 generation of teachers believe the retoric, that is hard to undo. Many teachers in my family, did some teacher training back in college in the early 90', s, spouse anon did teacher training 10 years ago; the training is whacked and no sane person can withstand crazy school bureaucracy. Changing the a system that big and that corrupt is even harder than changing the Federal Government because it is so decentralized.
