Liberals think their campaign against Wal-Mart is a way of introducing the subject of class into America's political argument, and they are more correct than they understand. Their campaign is liberalism as condescension. It is a philosophic repugnance toward markets, because consumer sovereignty results in the masses making messes. Liberals, aghast, see the choices Americans make with their dollars and their ballots and announce - yes, announce - that Americans are sorely in need of more supervision by... liberals.
