Pay more and treat teachers better. Market forces at work.
When I was growing up my father worked in an "elite" Westchester private school and my mother worked in the NYC DOE. The job fulfillment, administrative support and overall ease of working was like night and day between them.
She had a PhD, Masters, etc...
She would teach 2/5 days a week, and tell us to read the text book the other 3/5 days.
And her answer to anything libertarian was- That's fine, you can just build your own road, and put out your own fire.
Looking back on it, and believing her overly simplistic answers, I think a youtuber could have done a better job.
