Free enterprise: An economic system of business governed by the laws of supply and demand with minimal government interference, regulation, or subsidy.
Enterprises range from, for example, Lehman Brothers to a soup kitchen to Occupy Wall Street. Some enterprises are highly structured and highly organized; most enterprises have some structure and some organization; other enterprises are little more than collections of individuals, having no structure and no organization. It is worth noting that realist anarchist enterprises have some structure and some organization even though there are those who believe that idealist anarchist enterprises have no structure and no organization.
