The real problem is the insane policy of the U.S. to fund schools locally. That way, you will always have better schools in the richer areas and worse schools in the poorer areas.

In Ontario (Canada), schools are funded by the province. Schools doing worse can access addition funding and other resources. In 2020 teachers earned an average of $103,000/year including benefits. In Toronto, which has a high cost of living, the average was $108,000.

That's not to say that school quality doesn't vary, often by household income. Poorer people often have language issues (immigrants) and can't afford to pay for extra help for their kids, or don't have free time to work with them. The system is still stacked against them, but not nearly as badly.

The American "I got mine" method of school funding seems like the worst possible choice.
