Mr. Lieberman favors radical school choice. Mr. Flanigan's organization puts together poor students and sponsors who not only pay for them to go to private (mostly parochial) schools but also serve as mentors. Guests and host are agreed that the public schools are a mess; the question, in this provocative discussion, is the best and most politically feasible way to fix them. ML: "There is a movement now in this country for public-school choice [choice of schools, but limited to public schools]. I regard this as a big banana peel. Some conservatives favor it because they think it has some resemblance to the free-enterprise system, but the notion that you're going to get the benefits of free enterprise from choices offered by a public monopoly, I think, is ludicrous on the face of it."
