The country is run by senior citizens, and their control is transforming the nation. Samuel Moyn is Kent Professor of Law and History at Yale University and author of “Gerontocracy in America: How the Old Are Hoarding Power and Wealth and What to Do About It.” He joins host Krys Boyd to discuss why the nation’s elders hold vast amounts of wealth and political influence, why that isn’t transferring to younger generations and how we might rebalance power among generations. His companion article “The Old Guard” was published in Harper’s.
