Host Megan McArdle is joined by Robin Hanson, an economist at George Mason University and one of the earliest advocates for prediction markets. They discuss how betting markets compare with polls and experts, the risks of manipulation and insider trading, whether people should be able to bet on elections and wars, and what it would take for prediction markets to become a useful tool for business and government.

But some of America’s biggest fortunes are being built far from the spotlight: by auto dealers, contractors, beverage distributors and the owners of the unglamorous businesses that keep everyday life running. So who are these overlooked millionaires — and what do they tell us about opportunity in America?
There’s a lot to complain about in the American political system: Congress lurches from deadline to deadline, presidents claim more and more power and each side of the aisle treats the other as an existential threat. So how did our political system get this way—and what would it take to make it work again?
