We talk about socialism in America: where it comes from, what it means, why it's so associated with Bernie Sanders and whether it can actually reach the White House. What's the difference between democratic socialism and social democracy? How would the workers gain control of businesses like Facebook and Amazon? Who are the workers these days anyway? Plus, we ask what a Sanders vs Trump contest would actually be like. With Adom Getachew, from the University of Chicago, and Gary Gerstle.
