I went and saw Mayor Bill DeBlasio and economist Paul Krugman converse last night, in a moderated conversation about Inequality at the the Graduate Center of CUNY in the old Altman’s building at 5th Avenue. I was hoping to leap up and ask a killer question about infrastructure, but although I was sitting in the press section, I didn’t have a chance. When questions were asked, on index cards, the first was about the Clinton/Sanders race, or Hillary/Bernie race. Even I was a bit surprised that after an hour talking about inequality, both men essentially said they preferred Hillary, even though both acknowledged Bernie’s leadership on the issue. Of the two men, Krugman was more succinct and memorable, perhaps surprising given that he’s not a politician. The line of his that stuck with me, about Sanders: “Having your heart in the right place is not enough.” And also, that clear thinking and rigorous analysis also needs to be a progressive value. I turned on my recorder when the conversation got to politics, so here is about six minutes, with DeBlasio speaking first.
