A new book by Brink Lindsey and Steven Teles, The Captured Economy, contains important insights on how the U.S. copyright system impedes economic growth and promotes income inequality in America. Lindsey, vice president of the Niskanen Center, describes himself as a libertarian. Teles, a professor of political science at Johns Hopkins University, describes himself as a liberal. Their basic thesis is that powerful corporations and professionals use government regulation to eliminate competition and increase their wealth, thereby promoting inequality and slowing economic growth. Intellectual property law is one of their case studies.
