There is an element

of truth in this analysis by James Surowiecki.

See the excerpt

Considering that Wall Street firms spend all day dealing with the market, they have been slow to understand just how vulnerable they were to it. Companies like Lehman and, earlier, Bear Stearns saw going public as an excuse to take on more risk and act more recklessly, when in fact becoming a public company makes caution more important, since the margin for error is smaller, and the punishment for failure swifter. Now that the government has acted, Wall Street (or what remains of it) may yet be able to regain investors’ confidence. But long-term survival really depends on remembering the fundamental truth about playing with other people’s money: it’s a lot  of fun until they suddenly decide to ask for it back.
