Marxism
Marxists believe that humans' ability to produce goods and services today means people can move beyond the conflicts of a society that is divided into classes. Many Marxists believe that there will always be revolts and, with the right conditions, revolutions. In these revolutions, the workers will fight the capitalists. If they win, they will set up a socialist "workers' state" (a form of government where the workers are the rulers of society). This workers' state will only be temporary.  Its job will be to take power away from the capitalists, until all the capitalist countries in the world are defeated, and social classes no longer exist.
