Since time immemorial and pre-industrial, 'greed' has been the accusation hurled at the rich by the concrete-bound illiterates who were unable to conceive of the source of wealth or of the motivation of those who produce it.
If workers struggle for higher wages, this is hailed as "social gains", if businessmen struggle for higher profits, this is damned as "selfish greed".
If parasitism, favoritism, corruption, and greed for the unearned did not exist, a mixed economy would bring them into existence.
Capitalism has been called a system of greed—yet it is the system that raised the standard of living of its poorest citizens to heights no collectivist system has ever begun to equal, and no tribal gang can conceive of.
