I just read about some of your ideas regarding OOP and communism. One thing I really have to ask is: did you ever read any line of Marx, Engels, Lenin or any other material regarding communism? I believe that there is no assumption about human nature in these books, nowhere. If you are as familiar with OOP and pattern programming as you seem to be with communism than I don't know... You know what I mean?
