The correct answer is communism
Communism is a political and economic ideology contrary to capitalism. In fact, it is the negation of the concept of private ownership of capital.
From a historical point of view, communism would be the culmination of a long evolution of humanity. Thus, predecessor regimes, in particular, capitalism and socialism, would be responsible for increasing productivity.
Thus, it would allow for a kind of social, political and economic ordering. In such a way, inequalities responsible for the genesis of social problems, such as violence and misery, would be systematically abolished.
“Pure communism” seeks a classless, stateless and free from oppression society, so that decisions about what to produce and how to produce are democratically made.
However, Marxism was not, as is thought, the origin of communism. It dates back to Antiquity (tribal societies lived and still live in communism) and the Middle Ages, with Christian Communism or religious-communism and anarcho-communism.
