Another stunner from Matt Taibbi, and kudos to Rolling Stone for continuing to support his work. Just make sure to take your blood pressure medicine before you read it. It's long, but worth it:

What about the ratings agencies?

That's what "they" always say about the financial crisis and the teeming rat's nest of corruption it left behind. Everybody else got plenty of blame: the greed-fattened banks, the sleeping regulators, the unscrupulous mortgage hucksters like spray-tanned Countrywide ex-CEO Angelo Mozilo.

But what about the ratings agencies? Isn't it true that almost none of the fraud that's swallowed Wall Street in the past decade could have taken place without companies like Moody's and Standard & Poor's rubber-stamping it? Aren't they guilty, too?

Man, are they ever. And a lot more than even the least generous of us suspected.

Everything Is Rigged: The Biggest Price-Fixing Scandal Ever

Thanks to a mountain of evidence gathered for a pair of major lawsuits by the San Diego-based law firm Robbins Geller Rudman & Dowd, documents that for the most part have never been seen by the general public, we now know that the nation's two top ratings companies, Moody's and S&P, have for many years been shameless tools for the banks, willing to give just about anything a high rating in exchange for cash.

In incriminating e-mail after incriminating e-mail, executives and analysts from these companies are caught admitting their entire business model is crooked.

"Lord help our fucking scam . . . this has to be the stupidest place I have worked at," writes one Standard & Poor's executive. "As you know, I had difficulties explaining 'HOW' we got to those numbers since there is no science behind it," confesses a high-ranking S&P analyst. "If we are just going to make it up in order to rate deals, then quants [quantitative analysts] are of precious little value," complains another senior S&P man. "Let's hope we are all wealthy and retired by the time this house of card[s] falters," ruminates one more.

Yeah, you know who that Standard & Poor's exec is? A guy named Elwyn Wong, who's now working for the U.S. Office of the Comptroller Currency, our top federal banking regulator.

But no one did anything wrong, so move along now.
