This discussion, between Alan Greenspan and the brilliant Gillian Tett of the Financial Times, is well worth reading. It's an interview at the Council on Foreign Relations in New York two weeks ago.
The former Fed chairman comments on the difficulties he sees when the Fed needs to remove the easing it has applied. His comments on gold are maybe the most surprising of all. (He seems to love it.)
Surprising and thought-provoking stuff. I sent it to my clients recently.
(There is a video of the discussion online, too.)
