The Obama administration seems not to have a prosecutorial gene. It’s shy about calling a fraud a fraud when it occurs in high finance. This caution was exemplified most recently by the secretary of housing and urban development, Shaun Donovan, whose response to the public outcry over the banks’ foreclosure shenanigans was to take to The Huffington Post last weekend. “The notion that many of the very same institutions that helped cause this housing crisis may well be making it worse is not only frustrating  it’s shameful,” he wrote.

Well, yes! Obama couldn’t have said it more eloquently himself. But with all due respect to Secretary Donovan’s blogging finesse, he wasn’t promising action. He was just stroking the liberal base while the administration once again punted. In our new banking scandal, as in those before it, attorneys general in the states, where many pension funds were decimated by Wall Street Ponzi schemes, are pursuing the crimes Washington has not. The largest bill of reparations paid out by Bank of America for Countrywide’s deceptive mortgage practices  $8.4 billion  was to settle a suit by 11 state attorneys general on the warpath.

Since Obama has neither aggressively pursued the crash’s con men nor compellingly explained how they gamed the system, he sometimes looks as if he’s fronting for the industry even if he’s not. Voters are not only failing to give the White House credit for its economic successes but finding it guilty of transgressions it didn’t commit. The opposition is more than happy to pump up that confusion. When Mitch McConnell appeared on ABC’s “This Week” last month, he typically railed against the “extreme” government of “the last year and a half,” citing its takeover of banks as his first example. That this was utter fiction  the takeover took place two years ago, before Obama was president, with McConnell voting for it  went unchallenged by his questioner, Christiane Amanpour, and probably by many viewers inured to this big lie.

The real tragedy here, though, is not whatever happens in midterm elections. It’s the long-term prognosis for America. The obscene income inequality bequeathed by the three-decade rise of the financial industry has societal consequences graver than even the fundamental economic unfairness. When we reward financial engineers infinitely more than actual engineers, we “lure our most talented graduates to the largely unproductive chase” for Wall Street riches, as the economist Robert H. Frank wrote in The Times last weekend. Worse, Frank added, the continued squeeze on the middle class leads to a wholesale decline in the quality of American life  from more bankruptcy filings and divorces to a collapse in public services, whether road repair or education, that taxpayers will no longer support.

Even as the G.O.P. benefits from unlimited corporate campaign money, it’s pulling off the remarkable feat of persuading a large swath of anxious voters that it will lead a populist charge against the rulers of our economic pyramid  the banks, energy companies, insurance giants and other special interests underwriting its own candidates. Should those forces prevail, an America that still hasn’t remotely recovered from the worst hard times in 70 years will end up handing over even more power to those who greased the skids.

We can blame much of this turn of events on the deep pockets of oil billionaires like the Koch brothers and on the Supreme Court’s Citizens United decision, which freed corporations to try to buy any election they choose. But the Obama White House is hardly innocent. Its failure to hold the bust’s malefactors accountable has helped turn what should have been a clear-cut choice on Nov. 2 into a blurry contest between the party of big corporations and the party of business as usual.
