Context: From a comparative perspective, the United States is unusual if not unique in the lack of restraints on freedom of expression. It is also unusual in the range and effectiveness of methods employed to restrain freedom of thought... Where the voice of the people is heard, elite groups must insure their voice says the right things… The less the state is able to employ violence in the defense of the interest of the elite groups that effectively dominate it, the more it becomes necessary to devise techniques of ‘manufacture of consent’… Where obedience is guaranteed by violence, rulers may tend towards a ‘behaviourist’ conception; it is enough that people obey; what they think does not matter too much. Where the state lacks means of coercion, it is important to control what people think.
