University of Chicago Booth School of Business professor Luigi Zingales and Business Insider executive editor Sara Silverstein discuss comments made by imprisoned former pharmaceutical executive Martin Shkreli. Zingales says that while the pursuit of peak profits has become the corporate mantra, that isn't a hard-and-fast rule. He views Shkreli's assertion that profit maximization is the most important consideration as too narrow. Zingales then talks about how private companies often have considerations beyond profit, and tend to worry more about the well-being of employees.
