Joel Klein, via a kind reader’s email:

Barack Obama has been accused of “class warfare” because he favors closing several tax loopholes — socialism for the wealthy — as part of the deficit-cutting process. This is a curious charge: class warfare seems to be a one-way street in American politics. Over the past 30 years, the superwealthy have waged far more effective warfare against the poor and the middle class, via their tools in Congress, than the other way around. How else can one explain the fact that the oil companies, despite elephantine profits, are still subsidized by the federal government? How else can one explain the fact that hedge-fund managers pay lower tax rates than their file clerks? Or that farm subsidies originally meant for family farmers go to huge corporations that hardly need the help?
Actually, there is an additional explanation. Conservatives, like liberals, routinely take advantage of a structural flaw in the modern welfare state: there is no creative destruction when it comes to government programs. Both “liberal” and “conservative” subsidies linger in perpetuity, sometimes metastasizing into embarrassing giveaways. Even the best-intentioned programs are allowed to languish in waste and incompetence. Take, for example, the famed early-education program called Head Start. (See more about the Head Start reform process.)
The idea is, as Newt Gingrich might say, simple liberal social engineering. You take the million or so poorest 3- and 4-year-old children and give them a leg up on socialization and education by providing preschool for them; if it works, it saves money in the long run by producing fewer criminals and welfare recipients — and more productive citizens. Indeed, Head Start did work well in several pilot programs carefully run by professionals in the 1960s. And so it was “taken to scale,” as the wonks say, as part of Lyndon Johnson’s War on Poverty.
