>>13, Marx wasn't a genius. He simply didn't understand the functions of a capitalist society, because no uncorrupted capitalist society existed in his time. He tried to implement a system of government that pitted man against his nature, a good system is one that functions under the natural state of human intent, and that system is Capitalism. Unfortunately there isn't any capitalist system that isn't corrupted by socialism today.
