Andrew, u spelled imperfect wrong..... and the argument isn't really thought out...
1. You do not have to go through a Violent revolution to get anywhere, so revolution does not require a negative tone. And Many people would step down from power, The problem is yes, that humans lack the ability to work permanently for the greater good. And, you cannot expect a leader to stay righteous for his whole term, if he is allowed to lead alone. This is why you must instill a system of checks and balances.
2. you used a very bad example of communism... a better would be:
a doctor is getting paid just as much as a policeman, the policeman has a Much harder job, but in the long run, it is just as important as a doctors, (janitor vs. doctor works as well) but, they will get paid the same. So many people would not like this idea, due to the natural want for more that humans have.
And blaj, you can ask andrew, i changed all of my siblings diapers since i was old enough to talk, i basically raised my siblings. i fed them all, and i learned first hand that a child eats as much as it can, it takes the most toys it can find, and has to be taught to NOT do so. animals are the same way, the only creature we see everyday that follows the rules of communism are ants, and they are mindless working machines.
