We had the good fortune of chatting with Michael Sandel, the author of What Money Can't Buy: The Moral Limits of Markets. Sandel is the Anne T. and Robert M. Bass Professor of Government at the University of Harvard and his course on "Justice," the subject of his previous book, is one of the most popular courses at Harvard. In What Money Can't Buy, Sandel tackles a new question: what are the moral limits of markets? Should we pay kids to read? Is it okay to pay people to stand in line for us or test new drugs? He discusses this and more with Amazon's Darryl Campbell.
