Ajay Banga has spent a decade as chief executive of Mastercard. Last year, he oversaw $6.5 trillion in transactions. That means he knows what we’re spending right now (aggregated and anonymized, of course) and how long it might take to get us out of our current economic funk. It also means Mr. Banga has leverage over virtually any business that relies on credit card payments.For example, following recent reporting from New York Times columnist Nicholas Kristof on the scale of child pornography on PornHub, Mastercard announced that it would terminate payments on that site.

Mr. Banga departs as chief executive at the end of this year, transitioning to the post of executive chairman. In this “exit interview,” Kara Swisher presses him on whether the company he’s helped build can keep up with Silicon Valley — and with the social consciousness of the next consumer generation.
