Answer:
Karl Marx
Step-by-step explanation:
Many people only remember Marx for his theories about extreme socialist governments that eventually led to communism in other parts of the world. But he actually did understand how capitalism worked, added value theories, the way capital ($) worked, and he believed that capitalism was a necessary stage in the development of society. As an economist he was brilliant, but then he turned into a sort of philosopher.
Problems started when he said that after capitalism had led to an unprecedented economic growth, then it would be time for the workers (proletariat) to take over and lead economic systems. This rule by the working class would eventually lead to a fair society where everyone would be able to prosper.
Marx's economic theories are utopian, they call for a nearly perfect world, but humans aren't perfect. If you like Star Trek, you should recall that the world runs just like Marx wanted to. The economy and living conditions are based solely on your work, that is why the world was able to unite under one single federation. But as much as I would really like to travel at warp speed, it is not possible, and I really doubt that Marx's ideas are possible either.
