I’M LISTENING. . . . Hillary Clinton has an amazing plan to close every public school in America. “But she might want to sit in on a better-than-average math class before stating goals like this: ‘I wouldn’t keep any school open that wasn’t doing better than average.’ . . . Eventually we’ll be left with one, very good school, where students will learn the ways this is similar to and different from Zeno’s paradox. But this school, too, will have to be closed, because it will comprise the average on its own, and no school that isn’t doing better than average can stay open.”

Assign her some remedial reading.
