I have never been able to relate to the leftist' ideology and I always found it highly impractical and far too idealistic in this non ideal world that we live in (I often use the analogy of absence of ideal gas behavior in reality). I was always amazed that there were some people who believed in it and attempted at implementing them. Needless, to say, they have failed repeatedly, in every country such attempts were made - because man, by nature is unique and artificially clubbing them and homogenising them is a crazy adventure!
But I believe the best line that describes why communism failed is a letter written by somebody when the Berlin Wall was broken, to a newspaper editor. I read it in the Swaminomics column, yesterday in TOI. He has, in his inimitable style, chronicled the fall of Communism in World.
The letter captures the reason why so many people chose to leave 'the comfortable, full social welfare, and full employment, of East Germany and instead join the inequal, perilous world in West Germany' and I quote, "My daughter’s hamster (a pet white mouse) has food, water, shelter and even medical care, and a cage full of fun curly tubes. The hamster responds by constantly trying to chew his way to freedom. I think we all understand what freedom is, and it is not a gilded cage."
This is truly the Last word on Failure of Communism in the World
