There are tons of web resources - I don’t see any reason to send kids to school on a daily basis.
The teacher’s union would throw a hissy fit, but you could rotate students in for “specials” (art, athletics, whatever would be cheaper done in bulk or need group work)
You could lay off teachers in droves, as fewer would be needed. Taxes would decline (well, maybe not, but theoretically).
Our county had a home school support group. Once a week, all the families got together in a church. Parents volunteered to teach 1/2 to 1 hour classes. We had art teachers, music teachers, parents taught reading and math, etc. Everything a parent couldn't do or needed help doing was done there.
Eventually, the classes got so big, it had to split into two groups. It was a huge success. Parents appreciated the support they got from other parents.
As far as I know, they're still doing it. (My kids have already graduated college.)
