Communism, Socialism, and Capitalism

I was wondering what the class thinks about the different political systems in the world and what they think about how the government affects the individual and community. Why do some many of us look at communism or socialism with a evil eye. Is it because we have seen dreadful results or outcomes when countries were empowered by communistic or socialistic principles. But what about ourselves, the all mighty "free market" or capitalism. We have had our downfalls too. But the question I would like ask the class is which political system would ethically be more progressive. As for me I believe that a more Socialistic society and political system would benefit our society even more. For example there already some of the principles that are implemented in America, for example, hospitals, police, welfare, Social Security, etc are all services that are all provided to us from the government. But as you can see some of these simple services that are to help benefit us are being privatized by CEO's and the capitalistic powerhouse.
