It's another stab at public education. We already pay like 49th in the nation for teacher pay, I think they are trying to get rid of the pension system by making teachers independent contractors or something, and Florida has an $8000 voucher for "private school or homeschool expenses". So they currently pay you to subsidize a bit of tuition elsewhere, and make the quality of the teachers so low at the public option that starts to become more appealing as you see how badly the underfunded public schools are. And now, with vaccines only being like 97% effective, if you can afford to send your child to a private school (or just homeschool), you will. Why take a 3% chance your fully vaccinated child is going to get measles or polio if you can afford not to?
Then you nicely have your wealthy people who get a good education, and for the rest you have a population that consistently votes against their best interests because they are uneducated. Win all around for Republicans. I can't wait to leave this place.
