Gleichschaltung was not sufficient, but Nazi principles must continue to make the German people pure. Even Carl Jung's "collective unconscious" was preferred to Freudian concepts because of its communal element. The Volksgemeinschaft was also depicted in films on the home-front during World War II, with the war uniting all levels of society, as in the two most popular films of the Nazi era, Die grosse Liebe and Wunschkonzert. The Request Concert radio show, on which the latter film was based, achieved great popularity by broadcasting music claimed to be requested by men in the armed forces. Attempts to get women of "better classes" to take factory jobs were presented as breaking down class barriers and so helping create a true people's community. Failure to support the war was an anti-social act; this propaganda managed to bring arms production to a peak in 1944. Categories of Germans Nazi legal theory divided all Germans into two categories, namely the Volksgenossen ("National Comrades") who belonged to the Volksgemeinschaft and the Gemeinschaftsfremde ("Community Aliens") who did not. In addition to the duties and responsibilities shared by those in the community, the National Comrades were expected to build and create a "Volksgeist" ("Volk spirit") that would encompass the best aspects of the German people. As such, community aliens could not belong, since they were deemed an undermining element in the very foundations of the "Volksgemeinschaft". The modern German historian Detlev Peukert wrote the following about the purpose of Nazi social policy: The goal was an utopian Volksgemeinschaft, totally under police surveillance, in which any attempt at nonconformist behaviour, or even any hint or intention of such behaviour, would be visited with terror. Criminals, if deemed unable to be part of the people's community, were severely punished, even executed for crimes that did not provide for the death penalty, such as doubling the sentence the prosecution asked for when a defendant had not helped put out a fire, thus showing a disregard for the life of his "Volksgenossen" and community. In support of this, Peukert quoted two articles from the projected "Law for the Treatment of Community Aliens" of 1944, which though never implemented owing to bureaucratic quarrels showed the intentions of Nazi social policy: Children and youth In their desire to establish a total state, the Nazis understood the importance of “selling” their ideology to the youth. To accomplish this, Hitler established Nazi youth groups.
