A professor of public policy at Harvard, Robert D. Putnam has consulted for the last three American presidents and many other leaders around the globe. His newest book, "Our Kids: The American Dream in Crisis" is a groundbreaking examination of the growing inequality gap and explores why fewer Americans today have the opportunity for upward mobility. He has written fourteen books and been translated into more than twenty languages. His books "Bowling Alone" and "Making Democracy Work", are among the most cited publications in the social sciences in the last half century. This conversation between Putnam and Walter Isaacson, president and CEO of the Aspen Institute, was recorded live at the Institute's Alma and Joseph Gildenhorn Book Series.
