In Rolling Stone Issue 1082-83, Matt Taibbi takes on "the Wall Street Bubble Mafia" investment bank Goldman Sachs. The piece has generated controversy, with Goldman Sachs firing back that Taibbi's piece is "an hysterical compilation of conspiracy theories" and a spokesman adding, "We reject the assertion that we are inflators of bubbles and profiteers in busts, and we are painfully conscious of the importance in being a force for good." Taibbi shot back: "Goldman has its alumni pushing its views from the pulpit of the U.S. Treasury, the NYSE, the World Bank, and numerous other important posts; it also has former players fronting major TV shows. They have the ear of the president if they want it." Here, now, are excerpts from Matt Taibbi's piece and video of Taibbi exploring the key issues.
