In this special episode of the show Shermer and Green discuss one of the most important and yet poorly understood concepts in modern society: money and why it matters. They discuss: the origins of money, and how to make it work for you, how the stock market works, the power of compound interest, the secrets of millionaires, the difference between a IRA, 401(k), and a Roth IRA, hedge-fund managers and investment advisors, the relationship between risk and reward, the relationship between saving and spending, the problem with free market capitalism, money, happiness, and meaning, and the role of luck and contingency in how lives turn out.
