That there may lurk GOOD in EVIL is an old dialectical idea : the " " unity of opposites "

Way back in 1965 Black Muslim Malcolm X made a connection between racism and capitalism , between racism and imperialism ( long after the American Civil War ) . After 1865 the now " free " former Black slaves in the South were welcomed with open arms into the organized system of WAGE slavery up North. For more than 150 years the world social movement preached against the evils of CAPITALIST exploitation and oppression. Yet even Karl Marx wrote about the " progressive " side of WAGE slavery . It did free peasants from feudal " slavery ". It did develop the productive forces of human civilization. That there may lurk GOOD in EVIL is an old dialectical idea: the " unity of opposites " . My favorite Malcolm X quote : " Show me a capitalist and I will show you a blood sucker ".
