Yea - but maybe for such an important role for society we can actually put up the cash to make it a worthwhile career choice. I've heard the "we don't want teachers who are only in it for the cash" line enough that I want to puke. If you paid enough to attract the leeches legitimate teachers would get them sacked right quick.

It's not just about money. Ultimately, it's about respect. Considering the clearing price in a free market is good and all, but you have to consider there's a buyer representing real people, who determines the working condition of this group. And also a seller whose life will be made easier and more dignified if they're properly paid, which will in turn attract better and less desperate teachers.

When I say paid, I obviously also mean in intangible ways, such as having enough time to go to the toilet between classes. Or being insulated from being yelled at by parents and meekly saying sorry for telling off their particularly concentration-destroying kid.

If they were entirely not motivated by money, we could just have them do it for free. I think clearly teachers expect at least a little money, and perhaps many potential teachers would expect even more.
