Teachers vs engineers

"If we paid teachers like we paid engineers, just think how far ahead we would be!"

If we assessed teachers on the results of their work like we did for engineers, just imagine the outcry from the California Teachers Association.

"Class X results in Maths have plummeted year-on-year compared to equivalent classes Y, Z taught by other teachers; class X's Maths teacher objectively sucks and should be demoted/fired."
"How dare you! Won't you think of the children?"

I've met some great teachers in California, but The System is very clearly working against them.
