One of the great things about a free market is that it's inherently and indefatigably Darwinistic. Left to its own devices, a free market will eventually weed out the stupid from both 'ends' of the food chain otherwise described as supply and demand. As money is liberated from the hands of the stupid, those who would sell products or services to the stupid will eventually lose their share of the marketplace. Devoid of any 'benevolent' interference from government, the process is gloriously relentless, and cannot help but yield a successively smarter class of participants.
