Communism as Marx and Engels tell us, is the perfect social system. But to this day(Sep 19 2011), no nation on Earth has been able to apply it. Not the Soviet Union, not China, not Vietnam, not Cuba, not North Korea. NO ONE. Why? Because we are human, and many of us are GREEDY. You cannot remove greed from a human. Greed is a natural instict for survival. It´s in the human DNA. It´s in LIFE´s DNA. I am working in a social system that can work, but it requires technology. Such as robots that run on clean energy. Some tech required isn´t here yet. But we´re getting close.
