 You mentioned that you were at one time a Marxist and moved through this progression. I was kind of a Joan Baez Marxist, a tiny bit simple-minded. How did you change your mind? Well, very slowly. I mean, I was at Harvard College, Bernie Sanders and Jeremy Corbyn and I in, say, 1960. We're about the same age. We all had the same opinion. Capitalism is the problem. Let's have a revolution. The problem is that those two guys haven't changed their opinion. I've changed my opinion on lots of things, including my gender.
