In Chicago, sending your kids to Catholic school is hardly an indictment of the system. It's a very Catholic city. I went to Catholic primary school despite the local CPS K-8 probably being better (and despite my mom teaching there).

She's taking heat for it, obviously, but the heat is motivated: the CTU is intensely political, and has enemies. I'm not a fan. But my point stands: it doesn't really say anything about CPS policy that the head of CTU isn't a CPS customer.

I think at least the head of the group that represents public school teachers could find a single public school worthy of her own children. But apparently not

I'm not sure what you mean. There are obviously CPS schools with exceptional outcomes. I don't think anyone seriously believes that you can't do better than diocesan schools anywhere in CPS. This reads more like a dunk than analysis.

Yes, and the teachers also want better schools. That doesn't mean schools were better in the past.
