Sluggish economic growth poses a greater problem for the United States than income inequality. The featured speaker for Duke University’s latest Hayek Lecture delivered that message Tuesday on campus.

James Piereson is president of the William E. Simon Foundation and senior fellow at the Manhattan Institute.

Piereson acknowledges much of Piketty’s income data, but he explains in the video clip below why economic growth is a much more important issue for the United States today.
