I've lamented the fact that we are such small thinkers today. Our neighborhood public school is among the worst in the state. Local private schools cost about 1500/mo for gradeschool. I was looked at as a wild man for suggesting we should start our own school. 20 kids' worth of parents can afford to employ a teacher at a very attractive rate for both parties I suspect.
Local caring and local responsibility are key to any system of quality education. The public schools I grew up with in the American midwest (all lower middle class) were uniformly good but this was 50 years ago when such schools were widely funded by local sources (e.g., property taxes from the community), did not have to account to the distant bureaucracies or have to focus on prepping kids to meet minimum proficien…
This is really the only significant part of the equation. The system is basically designed to fail. You pass a tax levy for X mills, which brings in X amount of money for the school system, and never a dollar more. Property values go up, but property taxes do not. The budget therefore shrinks every year due to inflation, and every 10-15 years the situation gets so dire that the district has to put a ballot issue up for a tax "increase" to get funding back up to the levels of 10-15 years ago.
In most areas of the Midwest, this poor voter understanding of how schools are funded has resulted in a steady decline in school expenditures, even as actual costs of education have outpaced inflation.
