e.g., You can buy a Lambo for nearly one million but the cars salesman who sold it to you probably isn't rich.
But when you buy a painting for nearly one million, it'd make sense to think the actual painter is doing pretty well.
A (good)public school teacher in America is woefully underpaid compared to the service they provide. They should be paid similar to doctors & nurses, imho.
I can wholeheartedly assure you they are not as deserving as doctors, in large part because their training is much less rigorous, the job is much less demanding, requires less skill/ability, and a whole lot of teachers aren't "good" teachers. Just like any other profession, you have good, bad, and mostly average. The average teacher does not deserve nearly the same salary as the average doctor.
The teachers unions would go on strike if you tried to pay teachers based on performance or supply/demand (paying a CS teacher more than a gym teacher). And there's no way the average teacher deserves any more money than they're making now.
