In the earlier part of this century a certain group of people in the soviet union could not understand why their ideals had not been taken up by the rest of the world. so they started an investigation into western culture and society.Their conclusion was we were too set up and comfortable and secure for the idea of communisim to be attractive to us.now try if you can to look up 'The Frankfurth school' and you will be suprised
