Clergy have already called the outcomes for poor and minority students a scandal. Hopefully, we'll recognize the need to make the next step.
When considering how best to improve educational outcomes, what we pay teachers is not nearly as important as how they are paid. In 19th century England, the treatment of prisoners became a matter of great concern. Too many were dying on voyages to penal labor camps. The clergy called it a scandal. Parliament questioned the morality of ship captains. Then came a small policy change. Instead of being compensated per trip for transporting prisoners, ship captains were to be paid according to how many live prisoners were delivered. Problem solved.
Teacher compensation should be driven more by merit, productivity, and less on the level of education and seniority.
