Final answer:
Karl Marx believed that capitalism would collapse and be replaced by communism.
Step-by-step explanation:
Karl Marx believed that inequalities of capitalism would become so extreme that workers would eventually revolt. This would lead to the collapse of capitalism, which would be replaced by communism. Communism is an economic system under which there is no private or corporate ownership: everything is owned communally and distributed as needed. Marx believed that communism was a more equitable system than capitalism.
