Well. Public grade school teachers are, for sure, underpaid, at least in the US. And then, I'd hazard to say that at this point it is very possible that most people are underpaid in the US. Prices keep rising and the wages, for the most part, don't follow.I no longer prescribe to the overworked and underpaid notion. In some places and situations, this may be true, but it is far from universal. Except, of course, almost everybody tends to think they are underpaid and overworked. The only person I ever met who said they were underworked and overpaid was a prof. And he might've been drunk.
It's hard to find quality help in schools. The people who actually want to do a good job get overwhelmed (understaffing is also an issue) and the pay is not high enough, so they quit. Then you get people who don't care to fill the hole, making it all the more difficult for the ones who do care.
