Well, the ones tried were close enough. Soviets and the all eastern block, Cuba, Cambodia, China, North Korea. They all contained communist ideas such as common ownership, abolishing private property, central planning, and somewhat classless society. Apparently event the theory does not hold much weight as almost all collapsed or converted to some form of nationalist totalitarian regime. Perhaps once robots do all our jobs harvesting food and cleaning streets using power from endless battery fields, Marx&#x27;s prophecy of inescapable history will be fulfilled.
