Regimes that control people are successful in times of war or great economic depression. During these troubling times, people look for a leader and for solutions. When a charismatic leader comes along, therefore, people are ready to follow. Along with the propaganda of the media, this dynamic leader can restore hope and pride to a people. Such is the case with Adolph Hitler, who improved the German economy by building up manufacturing and employment through the military/industrial complex; he restored German pride with his ideal of the "Master Race," he engaged in a singleness of focus through the anti-Semitic propaganda that was employed as well as through other uses of propaganda.
This control of the media is essential to regimes such as that of the Nazis and Communists since it limits what the public in order to convey their message only and, thus, control the people. Those individuals who do not wish to "follow the crowd" and ingest the propaganda are punished or killed in such regimes. In the recent reign of Sadaam Hussein, for instance, hundreds of thousands of people were eliminated. Pol Pot of Cambodia executed two million people from 1975-1979. Of course, the "cultural revolution" of China cost millions of Chinese their lives as did Stalin's and Hitler's despotic regimes.
In these regimes, not only is there genocide, but individual rights are sacrificed. In short, the end of one's true humanity comes with such dangerous societies. For these reasons a film such as "Schindler's List" is, indeed, of paramount importance since even today we are witness to the tremendous affects that the media and political thinking can produce.
