Allison Benedikt’s anti-private-school manifesto is pretty entertaining: You are a bad person if you send your children to private school. Not bad like murderer bad—but bad like ruining-one-of-our-nation’s-most-essential-institutions-in-order-to-get-what’s-best-for-your-kid bad. So, pretty bad. I am not an education policy wonk: I’m just judgmental. But it seems to me that if every single parent sent every single child to public school, public schools would improve. This would not happen immediately. It could take generations. Your children and grandchildren might get mediocre educations in the meantime, but it will be worth it, for the eventual common good. Yes, this is a hyperbolic provocation. I agree with a lot of what Benedikt says, but I don’t think that private-school parents—or, for that matter, the many private-school teachers I know—are bad people.
