For tonight's Conversations with Great Minds - Thom is joined by David Korten. David is an economist, author, and former Professor of the Harvard Business School. His political activism has made him a prominent critic of corporate globalization. His 2006 book "The Great Turning: From Empire to Earth Community" argues that the development of empires about 5,000 years ago initiated unequal distribution of power and social benefits to a small portion of the population.
