Communism is a socialist social system in which the means of production are commonly owned, and which has no state, money, or social classes. It is also a political way of thinking and an idea of how to get to such a society. Communism says that the people of any and every place in the world should all own the factories and farms that are used to make goods and food. This social process is known as common ownership.
