In May 2009 Congress created a special commission to examine the causes of the financial crisis. Some commission members sought to block consideration of any historical account that might support efforts to rein in runaway bankers. One ... wrote [that] it was important that what they said "not undermine the ability of the new House G.O.P. to modify or repeal Dodd-Frank," the financial regulations introduced in 2010. Never mind what really happened; the party line, literally, required telling stories that would help Wall Street do it all over again. Which brings me to a new movie the enemies of financial regulation really, really don't want you to see. "The Big Short" is based on the Michael Lewis book of the same name, one of the few real best-sellers to emerge from the financial crisis. It does a terrific job of making Wall Street skulduggery entertaining. Many influential, seemingly authoritative players, from Alan Greenspan on down, insisted not only that there was no bubble but that no bubble was even possible. And the bubble whose existence they denied really was inflated largely via opaque financial schemes that in many cases amounted to outright fraud - and it is an outrage that basically nobody ended up being punished for those sins aside from innocent bystanders, namely the millions of workers who lost their jobs and the millions of families that lost their homes. While the movie gets the essentials of the financial crisis right, the true story of what happened is deeply inconvenient to some very rich and powerful people.
