Except that we have education requirements for teachers, and retail will hire just about anyone.
The reason teachers aren’t paid well is because we have a culture of funding public services like absolute shit. So despite low supply and high demand for teachers, we just keep adding more and more kids to each teacher, and giving them less and less supplies to work with. While letting wages stagnate.
People need to stop applying free-market thinking to our public services.
My school district is one of the few that pays a competitive wage to be private industry to their teachers in the U.S. The local teacher unions are extremely strong and have had numerous strikes over the years.
They unionized the non-certificated staff and they have gone on strike as well.
This past summer they were getting 100+ applicants for every open teacher position. Every open position is filled easily.
