I mostly agree with this. Good public schools are essential, even for people who don't have children in them. An educated population benefits everyone.Where we raised our chirruns (Memphis) the public schools are absolutely atrocious, both acaemically and socially. We tried private school, but that came with it's own compromises, so eventually we chose to homeschool. No regrets.
That said, I'm happy to pay property taxes that fund the public school system - did when we had younger kids and chose not to utitlze public education and do so now that our kids are all grown. We feel this way because good schools are fundmental to an educated society, which is what we want to live in.
That said, poor schools should be allowed to 'fail' - that doesn't mean tear it down and sell the land, but rather wholesale cleaning out of the administrators and teachers, as needed. This seems to be where the failure occurs the most (from the outside) - too many crappy administrators and teachers continue to remain employed at some level when they should be fired for poor performance. That's the part the market gets right, but GOOD public schools are absolutely needed.
Chronically failing schools should face real consequences. Leadership should be replaced, ineffective teachers should not be protected forever, and entire systems sometimes need to be rebuilt. My objection is pretending that simply handing out vouchers creates a fair market where every child suddenly has access to a great school.
Accountability matters. So does preserving a public system that is required to educate every child.
