“The last statement reveals more than may appear at first glance: it indicates that Greenspan's mistake was to expect that the lending institutions' enlightened self-interest would make them act more responsibly, more ethically, in order to avoid short-term self-propelling cycles of wild speculation which, sooner or later, burst like a bubble. In other words, his mistake concerned not the facts, the objective economic data or mechanisms; it concerned rather the ethical attitudes generated by market speculation—in particular the premise that market processes will spontaneously generate responsibility and trust, since it is in the long-term self-interest of the participants themselves to act thusly. Clearly, Greenspan's error was not only and not simply one of overestimating the rationality of market agents—that is, their ability to resist the temptation of making wild speculative gains. What he forgot to include in the equation was the financial speculators' quite rational expectation that the risks would be worth taking, since, in the event of a financial collapse, they could count on the state to cover their losses.”
