I’m a big fan of Paul Collier. A highly respected Oxford economist (and a knight!), he has spent his career trying to understand and alleviate global poverty. His book The Bottom Billion is still on the short list of books that I recommend to people, even though a lot has changed since it was published 12 years ago. So I was a little surprised when I learned that Collier’s latest book isn’t about poverty at all. But when I saw that it was about something I’m also keenly interested in—the polarization we’re seeing in the U.S., Europe, and other places—I was eager to see what he had to say. I’m glad I did. The Future of Capitalism: Facing the New Anxieties, is an ambitious and thought-provoking book.
