And now there are five -- five Wall Street behemoths, bigger than they were before the Great Meltdown, paying fatter salaries and bonuses to retain their so-called"talent," and raking in huge profits. The biggest difference between now and last October is these biggies didn't know then that they were too big to fail and the government would bail them out if they got into trouble. Now they do. And like a giant, gawking adolescent who's just discovered he can crash the Lexus convertible his rich dad gave him and the next morning have a new one waiting in his driveway courtesy of a dad who can't say no, the biggies will drive even faster now, taking even bigger risks.

What to do? Two ideas are floating around Washington, but only one is supported by the Treasury and the White House. Unfortunately, it's the wrong one.

The right idea is to break up the giant banks. I don't often agree with Alan Greenspan but he was right when he said last week that "(i)f they're too big to fail, they're too big." Greenspan noted that the government broke up Standard Oil in 1911, and what happened? "The individual parts became more valuable than the whole. Maybe that's what we need to do." (Historic footnote: Had Greenspan not supported in 1999 Congress's repeal of the Glass Stagall Act, which separated investment from commercial banking, we wouldn't be in the soup we're in to begin with.)

Former Fed Chair Paul Volcker, whose only problem is he's much too tall, last week told the New York Times he'd like to see the restoration of the Glass-Steagall Act provisions that would separate the financial giants' deposit-taking activities from their investment and trading businesses. If this separation went into effect, JPMorgan (JPM) Chase would have to give up the trading operations acquired from Bear Stearns (BSC). Bank of America (BAC) and Merrill Lynch (ML) would go back to being separate companies. And Goldman Sachs (GS) could no longer be a bank holding company.

But the Obama Administration doesn't agree with either Greenspan or Volcker. While it admits it doesn't want another bank bailout, its solution to the "too big to fail" problem doesn't go nearly far enough. In fact, it doesn't really go anywhere. The Administration would wait until a giant bank was in danger of failing and then put it into a process akin to bankruptcy.
