Capitalism has not changed place. It is still based on the exploitation of the working class. The conclusion Marx drew from this analysis is that the working class must overthrow the system and replace it with a classless society, which is even more necessary today than in his time. Many people who sincerely want to do something about the current state of the world feel that this pressure on the working class is far too narrow. We cannot simply observe the world we should try to enter into, as Marx did in the practical task of building a revolutionary party. If Marxism is right, then we must act accordingly.
