An American TV interview special in which Warren Buffet and Bill Gates, the two richest men in the world, field questions from business students on a variety of topics, ranging from ethics, money and globalisation to the secrets of their success. What do they consider to be the worst investment they ever made? What is the best piece of advice they've ever been given? How much money do they carry in their wallets? The two men answer all these questions and more with humour, insight and candour.
