Bharsta, As u mentioned Social Security is one of the example of socialist theory. In the same way steel industry ids protected. There have been so many times US bailed out failing compnies like caterpillar when they were faced with competition by Komatsu. I am just trying to pont out the extreme capitalist like US has some socialist elements. U agreed to the fact that communism cannot be successful. Thats what I want to point out. As far as maoism is concerned they are hard core communist. The tactics applied by them prove for themselves. Moreover their leadership is not honest. How can they justify the killings of innocents, extortion, attacks at infrastructure. We Nepalese are far better off when there is no communism.
