Well, technically, no. It would be nice if the world was more fair, and that folks earned salaries commeasureate with how much they aid society. But the inalienable right is to pursuit of happiness, not the actual happiness itself. Sorry, but it is possible to make choices that end you up in bad places.

Because teaching is a government job and society requires a lot of them, average teacher salaries are going to be the minimum level that produces a sufficient number of teachers
That's both theoretical, and oversimplified. We live instead in the practical and complex world.
In the real world, "sufficient number of teachers" is not a simple given. The number of teachers you need varies depending upon their quality, and upon what educational goals you set. You can try to meet a given goal with a large number of lesser teachers, or a smaller number of exemplary teachers, and so on. And, it isn't as if anyone really knows what number is sufficient until after the process is done. Administrators have to guess at how many people they need, and even an educated guess can be incorrect.
The idea that the system will, as a certainty, provide enough funds is purely theoretical. It depends upon the populace being enlightened and well-informed about the facts, and that no other agendas or market forces interfere. But in the real world, the populace doesn't grasp the economic theory, is poorly informed, and tend to be short-sighted. Economic realities can prevent even a willing populace from being able to pay monies sufficient to cover any particular educational goal.
