You say that there is no such thing as a communist regime (heh), but just to question: do you compare capitalism to fascism? I mean, I've read that a lot, and as an advocate of lassiez-faire capitalism, which necessarily requires a small, focused government that does not infringe on the rights of the people, it makes me laugh. Capitalism's pure opposite would be fascism. Communism is much more similar to fascism, because it denies individual liberty.
I've read The Communist Manifesto, and Marx makes some serious errors in his appraisal of the way society is run. What's sad is that there is a case to be said - most societies in the world at that time were in need of change, because they practiced capitalism with a class system based on inheritence (which is wrong, and destroys the virtues of capitalism). However, rather than explaining the importance of the workers as well, he goes on to denounce the "burgeoise", which is basically a hard-working individual who works for his own profit by trading his highest abilities with others. Yeah, really evil, Marx. Since the burgeoise didn't have to answer to the proletarian, he rallied the people to destroy ability for the sake of need. In other words, take over a factory, becuase somehow, a group of uneducated people know how to operate a factory without their managers. All right.
He created a morality that made it evil to be rich. Whereas you are paid for your virture in the lassiez-faire capitalist society, and you were rewarded for the amount you offered the world, communism states that to own money is an evil notion, and that the better you are the more reason you should sacrifice it. Then, he made the honest working man into a greedy moocher who sought to destroy achievement. Basically, he smurfed up the concept of both the rich and the poor and made them both villians.
There is a girl here, who was alive during the Soviet Union. She told me about her great-grandmother. In order to make enough to support her children, she set up a private enterprise, under the table, offering her services to the world in exchange for her children's lives. She was sent to Siberia, and when she came back, she was never the same. Her great-granddaughter, my friend, told me sadly, "She just wanted to be able to live. But it was said that those who wanted to really live wanted to do so at the expense of others." The idea was chilling.
But communism is motivated for a love of man, after all.
