The semi-annual occasion on which the tables are turned, and the guests become the interrogators--asked to focus, this time, on Mr. Buckley's new book, Four Reforms (the reforms being in the areas of welfare, taxation, education, and crime). One sample: WFB: "If you deny the philanthropic impulses of the American people, you are being anti-historical." KC: "I'd deny them." WFB: "Well, how do you account for $150 billion [a year in private philanthropy]?" KC: "Tax breaks." WFB: "I don't know where you went to school, but there were only three million people who paid income taxes in the Thirties, and yet practically every private institution, every church, every hospital was built. It was built by Americans. You all of a sudden think that charity was invented by FDR or something?" KC: "No, I just think that during the Thirties their guilt was a little bit larger."
