Cool. But people need to eat and our society (at least in the US) is completely run via cash - you can appeal to higher ideals all you want, but if you're starving out teachers you're going to lose a lot of the good ones that can go into other fields of education and communication.

I think a lot of teachers do value the experience of teaching enough that they'll stick with it through thick and thin - but a lot of folks never even consider teaching due to just how poor the wages are.
