Education again

Is it just me or do I write a lot about education? Anyway, Arnold Kling writes about education in his TCS column. One interesting problem that's pointed out is that, "as public school budgets have gone up, the number of people on the payroll actually involved in classroom teaching has plunged. During the 1949-50 school year, 70% of government school employees were teachers. Twenty years later (1969-70), only 60% of public school employees were teachers. By 1991, the percentage of teachers had dropped to close to 50%." Kling says we should scrap the President's No Child Left Behind Act and we should hope for competition as well as other potential solutions, an amusing one is number 5 where he proposes that we should try to lower government funding of education on the grounds that the government tends to be a very high-cost producer.
