Well, that's a nice, inflammatory sentiment, that has a comfortably anti-NEA flavor to it. And it's even correct, in some cases. But it's not universally true, and it's probably not even generally true.
For example, my experience was different, as is my kids'. I know a lot of kids from different states and places who are learning in schools that are about learning -- and yes, some of them are even public schools.
(FWIW, my brother's daughter is in a private school, and while it has a good reputation, he's dissatisfied with the education she's getting.... He says the school seems to be more about the elites, molding society.)
If you're really interested in fixing what's broke, you need to take an honest look at what's not broke. It's a lot more helpful than posting complaints to the FR choir.
It doesn't make sense to repair the brakes on a car that has a rotted body with an engine that doesn't run. You go out and get a different car, abandoning the junker. In other words, we homeschool versus trying to fix what we consider an "unsalvagable" educational system, for the good of our children.
Believe me, I have no interest in fixing schools. They should be blown up. Or sold off and converted to residential housing, or something.
If you want to know why I think schooling is satanic, read this book, by the 1991 NY State Teacher-of-the-year. (Yes, I said satanic).
