A short excerpt from P.J. O'Rourke:
The free market is just a measurement, a device to tell us what people are willing to pay for any given thing at any given moment. The free market is a bathroom scale. You may hate what you see when you step on the scale. "Jeeze, 230 pounds!" But you can't pass a law making yourself weigh 185. Liberals think you can. And voters--all the voters, right up to the tippy-top corner office of Goldman Sachs--think so too.
