Or do you mean the voters, who typically vote down attempts to increase the money for education budgets - typically because most taxpayers don't have children active in education.

There are no market forces at work here whatsoever.

One can look at private schools (including universities) and see this is not the case. The pay does increase slightly, but nowhere near proportionally to the value provided. A lot of that extra money provided by private citizens for their children's education is absorbed by bureaucracy (and football).

"If we fully deregulated education I bet you’d see teacher’s salaries rise."

I don't, not by a long shot.

"it’s disingenuous to suggest demand and its impact on price is “arbitrary”."

But that's not what I'm suggesting. Demand for teachers is pretty high. Pay has not risen to meet that demand, however. Demand for software engineers is also high, but only in some places has that demand correlated with a rise in salary.

It is completely arbitrary.
