As the documentary says, people are taught to respect and obey authority. The entire school system, military service and corporate world are exercises in surrendering your will and intelligence to a figure of authority, no matter whether they're right or wrong. As long as those systems are the norm, of course people will do what they're told.
Good documentary, in any case.
