There is not doubt that Larry Summers is excited by October G-20 and IMF meetings as the top policy makers meet to discuss the state of the world economy and other significant global interests. It’s a time when the media is focused on the world’s leaders and Mr. Summers likes the role of being a major player. There is no question about Summer’s academic qualifications and his wealth of policy making experience. If success in the field of economics was based on eugenics, well, Larry Summers would certainly have a Nobel Prize. My one major criticism of Secretary Summers was his running interference for Robert Rubin and Sandy Weil in their efforts to repeal Glass-Steagall, which even Mr. Weil has admitted was a great mistake. In today’s Financial Times, Larry Summers had an op-ed, “Why Public Investment Really Is A Free Lunch.”
