Karl Marx And The Industrial Revolution

Karl Marx was a great philosopher, social scientist, historian and revolutianary figure. He is known for creating or spreading the idea of communism. It was meant to have everybody have the same amount of money; not to make the rich richer, and the poor poorer.  He had an idea of everybody being treated equal and everybody having possesion of the same things.  This idea sounds perfect when you say it.  But when you test it, it is much more different; why? because there are the ones who work ALOT, and there are the ones who work A LITTLE.  So it really is not fair if a professional doctor makes the same amount of money as an 18 year old handing out flyers.  There is always going to be a competition or a "greedy" one who wants to make more money then the rest.  This is why Marx idea wasn't spread out world wide.
