Some public schools absolutely are shit. And we've got a wealth of propaganda invested in selling "education as a luxury service" rather than a public utility.

The marketing strategy of homeschool sellers is to convince people that working with your PTA is a waste of time and only you know how to adequately teach your kids.

Ideally, education isn't some singular struggle, but a group effort. I've learned more and faster in small groups with a talented TA and enthusiastic professor than in any independent study.
