Wall Street is its own worst enemy. It's busily shredding new regulations and making the public more distrustful than ever. The Street's biggest lobbying groups have just filed a lawsuit against the Commodities Futures Trading Commission, seeking to overturn its new rule limiting speculative trading in food, oil and other commodities. The Street makes bundles from these bets, but they have raised costs for consumers. In other words, a small portion of what you and I pay for food and energy has been going into the pockets of Wall Street. Just another redistribution from the middle class and the poor to the top. The Street argues that the commission's cost-benefit analysis wasn't adequate. Putting the question into the laps of federal judges gives the Street a huge tactical advantage because the Street has almost an infinite amount of money to hire so-called experts" who will say benefits have been exaggerated and costs underestimated. But when it comes to regulating Wall Street, one big cost doesn't make it into any individual weighing: the public's mounting distrust of the entire economic system, generated by the Street's repeated abuse of the public's trust. Wall Street's shenanigans have convinced a large portion of America that the economic game is rigged. Wall Street has blanketed America in a miasma of cynicism.
