It's a wonder anyone wants to do the job at all, knowing all this in advance. I almost became a teacher once. Figured all the abuse would be a degrading waste of my efforts.
The point was what makes it worthwhile isn't cash.
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.
Most people are not motivated by money, they reluctantly accept that they need to earn a living, but it is not a big driver per se in most people I know.
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.
