Who is “we?” If he means folks who voluntarily send their kids to government schools, then the answer is of course not.
There are three groups of parents who send their kids to government schools:
1. The unfortunate ones who cannot send them anywhere else.
2. The clueless ones who in spite of the overwhelming amount of damning information choose to send their kids to government schools.
3. The complicit who are just fine with what is going on.
While I respect Mr. Sowell, I think that his awesome intellect would be better spent figuring out ways to get the parents in group 1. into private schools or homeschooling.
You forgot the fourth group: Those that run towards gunfire (while others run from gunfire).
