When Alan Greenspan began his political career in 1974, he asked two people to accompany him to his Oval Office swearing-in ceremony as chairman of the Council of Economic Advisers: his mother, Rose Goldsmith, and his guru, Ayn Rand. From the time of his appointment years later as Federal Reserve chair until his retirement in 2006, Greenspan would implement Rand’s ideology of “objectivism” as monetary policy: Counting on market players to self-regulate in the pursuit of their selfish interests, he deregulated the financial industry and scoffed in the late 1990s when warned of the systemic risks posed by the unregulated derivatives market.
