Final answer:
Karl Marx predicted that capitalism would collapse due to its own inequalities, leading to a worldwide communist revolution that would establish an equitable society. However, this global revolution and the subsequent classless society Marx envisioned never occurred.
Step-by-step explanation:
Karl Marx made several predictions about the future of capitalism and its eventual replacement. Among these, Marx foretold that the inequalities of capitalism would become so severe that the workers would revolt, leading to the collapse of capitalism, substituted by communism. This would result in a classless society where all property is owned communally and distributed according to need. Marx's vision embraced the concept that communism would create a more equitable, classless society without private property, contrasting capitalism's exploitative nature. Despite his predictions, the global communist revolution he anticipated never materialized; instead, what occurred was a variety of communist and socialist revolutions that neither achieved the economic nor political equality Marx envisioned.
