We are assembled here on the lawn of Planet Money University for the greatest graduation in history - because it features the greatest economic minds in history. We'll hear from Adam Smith, Karl Marx, John Maynard Keynes, and some surprising guests as they teach us a little bit more economics, and offer a lot of life advice. But first, we have to wrap up our (somewhat) complete economic history of the world. We'll catch up on the last fifty years or so of human achievement and ask ourselves, has economics made life better for us all? This series is hosted by Robert Smith and produced by Audrey Dilling. Our project manager is Devin Mellor. This episode was edited by Planet Money Executive Producer Alex Goldmark and fact-checked by Sofia Shchukina.
