According to Joris Luyendijk
In other words, Greenspan had been unable to imagine that bankers would run their own bank into the ground. Had the maestro read the tiny pile of books by financial anthropologists he may have found it easier to imagine such behaviour. Then he would have known that over past decades banks had adopted a “zero job security” hire-and-fire culture, breeding a “zero-loyalty” mentality that can be summarised as: “If you can be out of the door in five minutes, your horizon becomes five minutes.”
While this was apparently new to Greenspan it was not to anthropologist Karen Ho, who did years of fieldwork at a Wall Street bank. Her book Liquidated emphasises the pivotal role of zero job security at Wall Street (the same system governs the City of London). The financial sociologist Vincent Lépinay’s Codes of Finance, a book about the division in a French bank for complex financial products, describes in convincing detail how institutional memory suffers when people switch jobs frequently and at short notice.
