It was characteristic of the economic system of the nineteenth century that it was institutionally distinct from the rest of society. In a market economy, the production and distribution of material goods is carried on through a self-regulating system of markets, governed by laws of its own, the so-called laws of supply and demand, moti­vated in the last resort by two simple incentives, fear of hunger and hope of gain. This institutional arrangement is thus separate from the noneconomic institutions of society: its kinship organization and its political and religious systems. Neither the blood tie, nor legal compulsion, nor religious obligation, nor fealty, nor magic created the sociologically defined situations that insured the participation of individuals in the system. They were, rather, the creation of institutions like private property in the means of production and the wage system operating on purely economic incentives.
