"Most of Marx's predictions have failed to materialize, and his labor theory of value and other ideas have been proven wrong. Marx failed to recognize the incentive system built into the capitalist model - consumer choice and the profit motive of the entrepreneur. The irony is that capitalism, not socialism or Marxism, that has liberated the worker from the chains of poverty, monopoly, war, and oppression, and has better achieved Marx's vision of a millennium of hope, peace, abundance, leisure, and aesthetic expression for the 'full' human being."
