Samantha Hancox-Li and guest David Lay Williams, author of The Greatest of All Plagues, discuss the nature of extreme wealth inequality in America and across history, from Plato to Occupy Wall Street. Williams argues that extreme wealth warps the soul, leading to "pleonexia"--a restless desire for more and more that will never be fulfilled. Reducing wealth inequality is therefore not about redistribution or envy, but rather self-protection against overweening power.
