A jobs profitability and a jobs worth to society are very often unrelated.
Lots of jobs ultimately contribute nothing to the world;
but pay excessively well.
eg. . Playing in the NBA. Or running a successful TGP.
Other important jobs are rewarded by the market.
eg. Doctors. Researchers. Architects.
Still more don't pay what they are worth.
such as the Teacher example.
If you don't reward these positions well enough,
you get a lower quality of people filling them.
In todays high schools,
the best teachers think they're babysitters,
and the rest think they're prison gaurds.
It's no surprise the kids come out acting like prison inmates.
However if you made those jobs some of the best paying in our
society, and made the qualifications so high, and the compeition
so fierce, that only our smartest citizens were teaching our future
citzens, it would turn out a better class of people and even pay
off economically in the longterm.
But now I'm offtopic.
IMO if you cannot force the market to reward lower-income jobs;
you can at least give people in those positions a break on taxes.
Civilization simply wouldn't work if everyone was a basketball player,
or an adult webmaster, or a camgirl, so we should all be greatful
other people are busy doing real work. We do owe them.
