Would sure hate to be a gay kid. At least with public education in that case, there's a small hope of exposure to the greater world.

You end up with private schools with competitive admissions and terrible schools for the remnants, then, if you go with a 100% voucher approach. The expensive to teach students (with disabilities, needing educational & behavioral interventions, etc) and those with absent / uncooperative students all cluster in one public backstop that almost certainly doesn't work well.

I say this as a teacher in a private school. I'm well aware that my job is educator "easy mode" in many ways.

Perhaps partial vouchers -- you get 30%-50% of what the state spends on an average student-- could help to expand choice and diversity in education while keeping a system of universal education intact. But 100% vouchers are a recipe for disaster IMO.

The problem of given that choice is that smart people will go to strong academic schools.

Then Billions wasted on "reducing the differences" will show that people want and choose to be different.

Then various narratives will die in the cemetery of good intentions...

This is a terrible approach. Unless of course you’re ok with leaving the poor and handicapped and otherwise different kids behind.
