Where I live, public school teachers are paid a pretty nice salary, average about $70K per year, which is well above the average worker's pay where I live. So, I think they're paid just about right here. A good salary for hard work, and teaching is not easy, despite what some people think.
I do wish the guaranteed pensions would be done away with. They're simply not sustainable. They should have their own personally funded 401K, the growth (or non-growth or loss) of which is determined by the stock market, like the vast majority in the private sector. I think that will happen sooner than later.
