Ayn Rand died in 1982 but she's going through a revival. Her books "The Fountainhead" and "Atlas Shrugged" still sell hundreds of thousands of copies. "The Fountainhead" also endures on DVD. And now there's a new biography by Anne Heller called "Ayn Rand and the World She Made." Anne Strainchamps talked with Anne Heller about her subject, the power of capitalism, and her appeal for young people.
