Critics of capitalism love to bash it as mean and unfair — all about greed and self-interest. But one local academic says that self-interest plays a key role in meeting the needs of the public. In this video clip, Dr. Mark Steckbeck, assistant professor of economics at Campbell University, discusses the role of competition in guiding people to produce for others as they pursue their own self-interest. Steckbeck offered these comments during a June 16, 2014, speech for the John Locke Foundation’s Shaftesbury Society.
