What people continuously insist on not understanding (both self-claimed socialists and capitalists) is that capitalism is supposed to be much better than earlier systems. This is the central argument of Marx. He claims the world is in a never-ending struggle between social classes. It's very obvious that capitalism is better than older systems because it's the product of earlier conflicts; so your argument does not mean anything to me. The idea is to make it even better.
