Stewart interviews Edward Glaeser, the Harvard economist, who comes to promote his book  Triumph of the City: How Our Greatest Invention Makes Us Richer, Smarter, Greener, Healthier, and Happier.

Glaeser argues that cities mean we get to learn from each other face to face. In my city, there's a lot of poverty and homelessness, hate crimes and domestic violence, and it seems to me that people are desensitized to these issues.  Glaeser's focus in the interview (and, seemingly, the book) is on the "good", the triumph of the city. He speaks about clean water, renting vs. owning, and transportation, and he makes some good points.  However,  I am unsure, after listening to this interview, what else his book has to offer.
