A politico-economic system in which the owners of the most capital (means of production) use the government to steal the private property of the masses (often in the name of private property) via such measures as eminent domain, self-serving regulation, confiscatory taxation, inflationary spending, corporate bailouts, "too big to fail" doctrines, etc., in order to maintain their own position at the top of the wealth hierarchy.
2. A misnomer for the system combining social cooperation in the division of labor with respect for the private property of all, big and small. Properly called the free market.
