Microsoft CEO Satya Nadella firmly believes that his company must do more than make money - it has a social purpose too. And failing to fulfill that purpose may put capitalism itself in danger. It's an idea that's been most recently popularized by author Colin Mayer. In the inaugural episode of Leadership Next, Alan Murray speaks to both Nadella and Mayer, exploring the role business must play in the 21st century. Also featured, insight from Fortune's Andrew Nusca, who profiled Nadella for the magazine in 2016 and then again last month.
