I'm happy to pay taxes for a public education system that works. Unfortunately, what we have today is a system encumbered by too many administrators, hampered by unfunded mandates, exploited by public unions, and micromanaged from every level from (superfluous) department heads to district administration to state legislators to the federal government.
From 2010-2019, the number of administrators in public schools nearly doubled, while the number of students and teachers only went up by ~8%. Those administrators generally cost a whole lot more than classroom teachers. To justify their salaries (and their staff), they are always chasing the latest fads in public education, whether it's "social emotional learning," Chromebooks, "student support time," AVID, teaching kids to "analyze texts", abandoning math facts and phonics, or "diversity/equity/inclusion" programs, each at tremendous expense both in dollars and disruption. The amount of inefficiency and waste is staggering.
And that's just on the local level. State and federal mandates, or "money with strings attached," adds tremendously to the cost, while burdening the actual teaching. What have we got in return for these enormous costs? Just about nothing. Part of the problem is that, since it's a government program, all the political incentives are front-loaded, and there's little incentive to review what has been done, and to weed out what isn't working. NCLB didn't move the needle. Neither did ESSA. Common Core was a disaster, and Race to the Top didn't help, either. More standardized tests, and linking funds to test scores, only provided perverse incentives. But we are still operating under the burdens they imposed.
