The main problem with teaching is that there's many people who can do it. If you compound the issue with paying teachers $150k a year, not only would the cost of education skyrocket, you would be running into more and more people unemployed but with a degree specifically meant for teaching.

In many school systems though, if your teacher has an average score below the national average, you can't do anything about it.
