Edward L. Glaeser discusses how the proliferation of unfair laws and regulations is walling off opportunity in America's greatest cities at the Manhattan Institute’s 2019 James Q. Wilson Lecture. We like to think of American cities as incubators of opportunity, and this has often been true—but today's successful city-dwellers are making it harder for others to follow their example. In this year's Wilson Lecture, Glaeser addresses the conflict between entrenched interests and newcomers in its economic, political, geographic, and generational dimensions. Video can be found at the Manhattan Institute website. Glaeser is the Fred and Eleanor Glimp Professor of Economics at Harvard University (where he has taught since 1992), a senior fellow at the Manhattan Institute, a contributing editor of City Journal, and the author of Triumph of the City.
