Economist Tyler Cowen is disdainful of social media, heartened by recent immigrants, and wary of pot. He thinks that, in our collective desire for comfort, we are postponing big and necessary changes that will sow instability in the years ahead.

Cowen's latest book is The Complacent Class. In the Spiel, are things going any better abroad? Learn more about your ad choices. Visit podcastchoices.com/adchoices
