This is in response to comments on some previous posts about teachers’ unions and other matters.
1. The U.S. leads the world in health care spending per person, but not in health care outcomes. Many people look at that and say that health care costs too much in the U.S., and we should be able to get the same our better outcomes by sending less. Maybe that is correct, maybe not. That is not the point here. But–
2. the U.S. leads the world in K-12 education spending per student, but not in student outcomes. Yet nobody, says that education costs too much and that we should spend less. Except–
3. me. I believe that we spend way too much on K-12 education.
4. We spend as much as we do on education in part because it is a sacred cow. We want to show that we care about children. (Yes, “showing that you care” is also Robin Hanson’s explanation for health care spending.)
5. We also spend as much as we do because of teachers’ unions. They engage in featherbedding, adding all sorts of non-teaching staff to school payrolls (and adding more union members in the process). In Montgomery`County, last time I looked, there was one person on the payroll for every 6 students, but there were more than 25 students per classroom teacher. That is why I do not think that cost disease, as discussed recently by Scott Alexander, is the full story. It’s not just that it’s hard to raise productivity in teaching. It’s that teachers’ unions cut down on productivity by continually getting schools to add non-teaching staff.
6. If I could have my way, the government would get out of the schooling business.
7. If we wish to subsidize education, we should do it through vouchers. Note that this could be done on a progressive basis, with the size of the voucher a declining function of parent’s income.
8. I do not expect educational outcomes to be any better under a voucher system. That is because I believe in the Null Hypothesis, which is that educational interventions do not make a difference.
9. However, a competitive market in education would drive down costs, so that the U.S. would get the same outcomes with much less spending.
A few additional notes:
10. When parents seek out schools with good reputations, they are going after schools where most of the students come from affluent families. The schools themselves do not do much.
11. Even within income-diverse school districts, affluent parents figure out a way to keep their kids from being surrounded by poor children.
12. I have grown increasingly uncomfortable with the leftist ideology preached in government schools.
