Those same people also make smart decisions without transparency  smart for them, if not the country. Even if the reform bill does bring stringent regulation to derivatives  a big if  that won’t rectify capitalism’s worst “innovation” in our own Gilded Age: the advent of exotic, speculative “investments” that have no redeeming social value and are instead concocted to facilitate gambling for its own sake. Such are the Goldman instruments of mass financial destruction that paid off for John Paulson. In 2007 alone, according to Gregory Zuckerman in his book “The Greatest Trade Ever,” Paulson’s personal take amounted to over $10 million a day, “more than the earnings of J. K. Rowling, Oprah Winfrey and Tiger Woods put together.” That “financial alchemy,” as Zuckerman calls it, explains why the finance sector’s share of domestic corporate profits, never higher than 16 percent until 1986, hit 41 percent in the last decade.

As many have said  though not many politicians in either party  something is fundamentally amiss in a financial culture that thrives on “products” that create nothing and produce nothing except new ways to make bigger bets and stack the deck in favor of the house. “At least in an actual casino, the damage is contained to gamblers,” wrote the financial journalist Roger Lowenstein in The Times Magazine last month. This catastrophe cost the economy eight million jobs.

Lowenstein argued for a transfer tax on financial trading, a reform that has found favor with Britain’s prime minister, Gordon Brown, if not our own Treasury secretary, Timothy Geithner. Equally compelling is the notion articulated by Ryan Avent, a blogger at The Economist, that “public anger” and “hooting derision” be increased to shame Wall Street into changing its ethos. This assumes, of course, that there is any capacity for shame. Perhaps the most productive tactic comes from Ted Kaufman, Democrat of Delaware, who is using his lame-duck residence in the Senate (as the appointee to Joe Biden’s old seat) to demand that we root out the “fraud and potential criminal conduct” that “were at the heart of the financial crisis.”

To achieve this overdue reckoning will require action  by the S.E.C., the Justice Department and any other legal authority that wants to get into the act. That no one at Lehman Brothers has yet been held liable for its Enronesque bookkeeping deceit is appalling. That we still haven’t seen the e-mail and documents that would illuminate A.I.G.’s machinations with Goldman and the rest of its counterparties amounts to a cover-up. That investigative journalists have consistently been way ahead of the authorities, the S.E.C. included, in uncovering Wall Street’s foul play is a scandal. If this culture remains in place, the whole crisis will have gone to waste.

As a reminder of the unchastened status quo, Blankfein remains the gift that keeps on giving. On Thursday, The Financial Times reported that he had been calling clients to argue that the S.E.C. case against Goldman would ultimately “hurt America.” The opposing point of view was presented by Ira Glass on his radio show “This American Life” this month. With reporters from the nonprofit journalistic organization ProPublica, it told the story of another hedge fund, Magnetar, that gamed the housing bubble. Bankers who worked on Magnetar deals walked away with their huge bonuses well before disaster struck  or, as the program put it, “bankers made money even when they were buying things that eventually blew up the bank.” Not to mention the economy. And it was all legal.

To award the audience a bonus, “This American Life” concluded with a Broadway song commissioned from a co- author of the satirical musical “Avenue Q.” Titled “Bet Against the American Dream,” it distills a complex financial saga to its essence: Those who shorted the housing market shorted the country.

Go online, listen to it and laugh. But the fact remains that those who truly hurt America are laughing harder still, all the way to the bank.
