Well, a quite interesting discussion started in the lounge about these topics.
Yes, Marx can be seen as father of all communism, but it was never his intention to create communism. There is a huge difference between marxism and communism. One can say that the idea of Marx put into practice can be called communism. The idea was good.....what people made of it isn't. Communism is most certainly NOT socialism. Those two things get mixed up very often, but are in reality quite different. Communism is about absolute equality, which doesn't work because there are always people who want more and have the means to get more. Socialism is about equality too, agreed, but not in the same way ; socialism says that the people who are most capable of leading a nation( for example) should do everything to make it as good as possible for everyone, they should live for the people so to speak.
