Free market capitalism is an economic system of production, whereby each man owns the product of his own labors and, therefore, has great economic incentives to produce both for himself, his family, and as surplus goods to trade for the surplus product of others. Even under life and death threats neither the socialist worker nor his overseer would know what to produce, how to produce it, or in what quantities and qualities. These economic cues are the product of free market capitalism and money prices.
