On this episode of ZigZag, host Manoush Zomorodi is joined by Eric Ries, who went from writing Silicon Valley's bible to building a stock market for social justice. Together, they examine why quarterly earnings reports cause anti-social behavior and how a new stock exchange in the US might present a systemic solution. As Eric says, this "will serve as inspiration to a new generation of civic entrepreneurs who will say: We don't have to take the institutions of our society as a given. We could try to build new and better ones." ZigZag, the business show about being human, is now a member of the TED family of podcasts. Listen or subscribe wherever you get your podcasts.
