“...The public schools could do this as well if they got their act together...”
Nope, NEVER going to happen. IMO, you hit everywhere BUT on the head.
What you note is the difference when one gets away from ‘single/3rd-party payer’ education.
When people pay out of their own pockets....people CARE about results, decorum, curriculum, teachers, student behavior, etc.
Again, that can NEVER be in *FREE* ‘public’ education.
The public schools used to do this routinely. In many places, they still do. But I agree that governance is the issue, and school choice is the solution.
