"…A government as large as the modern megastate cannot conceivably be controlled by a well-informed public, since it is literally impossible to be knowledgeable about even a fraction of the many complex matters modern governments are called upon to govern. … The attraction of free markets … is that they have self-correcting features that place far smaller demands on anyone’s knowledge than democracy does. Each person concerns herself with her own life and the system, supposedly, runs itself. Interpreted in this way, the literature on public ignorance could form the basis of the consequentialist argument the postwar free-market economists sought, but never found … against all government economic intervention: for even if it cannot be shown, on economic grounds, that every intervention hurts more than it helps, it might be shown, on political grounds, that by opening the door to helpful interventions, we begin sliding toward the unhelpful ones on a slope slippery with public ignorance."
