I personally believe that communism is an idealist's dream; a literal utopia, a world of equality, peace and prosperity, yet it is only a dream. On a basic psychological stand point, it is simply human nature to want to be better than the next bloke, to be more wealthy, to be more powerful. The very nature of communism is an ideal place for those with low morals, those who are so easily corrupted by greed, to take and abuse power. This is evidenced in the suffering of the millions under Stalin's oppression, China's gradually loosened stranglehold of it's people, and all the other myriad regimes that have flourished and fallen under their own corrupt diseases. These are the men who gain their power and become drunk with it, and will do anything to keep it and the "order" that goes with it, as shown by the Tienanmen square massacre and the millions that Stalin put to death.
Communism could work, it could create a perfect society, only if those who inhabited it were perfect themselves, without vice, greed or ambition, traits inherit in the human being.
A passage in a book I had to read for school goes along the lines of "In the distance, communism looks like a diamond, but close up it is a tear." and while that is being considered, think of this, think of all those who have died for communism's perfect society, all those deemed unhealthy for the regime, those who died for dark, diseased and corrupt regimes that allowed many and varied madmen to flourish, and ask yourself, is humanity truly ready for a perfect world? Or are we simply to blinkered by our hatred and prejudices to see our follies and turn our backs on it, and move forward into, and what could be, the most prosperous time this world has ever seen.
and somehow this turned into a feature length presentation somewhere...
this is just my own, hopefully not too biased opinion, and i hope it doesn't get torn apart to badly.
Note: i've got nothing against communists, just tyrannical dictators.
