One channel of influence was, of course, the flow of individuals between Wall Street and Washington. Robert Rubin, once the co-chairman of Goldman Sachs, served in Washington as Treasury secretary under Clinton, and later became chairman of Citigroup’s executive committee. Henry Paulson, CEO of Goldman Sachs during the long boom, became Treasury secretary under George W.Bush. John Snow, Paulson’s predecessor, left to become chairman of Cerberus Capital Management, a large private-equity firm that also counts Dan Quayle among its executives. Alan Greenspan, after leaving the Federal Reserve, became a consultant to Pimco, perhaps the biggest player in international bond markets.
These personal connections were multiplied many times over at the lower levels of the past three presidential administrations, strengthening the ties between Washington and Wall Street.
