The business world is abuzz today about Greg Smith’s parting shot at his long-time employer, Goldman Sachs. Is it accurate? Hard to say, but it has the ring of truth. We know that Goldman has made some unfortunate decisions in serving clients (such as Fabrice Tourre’s disparaging derivatives while pushing them to clients, and the firm’s taking both sides in the El Paso/Kinder Morgan deal). This doesn’t necessarily make Goldman any different from the rest of Wall Street. I remember being repelled by how traders at Salomon Brothers referred to their clients in Michael Lewis’ 1989 book Liar’s Poker.
