When you watch this film, you will be told multiple times that the purpose of the film is unknown. Yet, when you listen to the description of how the film was made, and consider that propaganda was the intent of the film, I think that the purpose is understandable. Imagine that the film portrays not a controlled situation, rather an isolated situation; for, the Nazi presentation of the film would not have portrayed the situation as having been staged or controlled, rather the Nazi presentation would have purported to merely show Jews living in isolation from the outside world. The Nazi presentation would pretend to show how Jews interacted socially and economically when living together and establishing their own system of order. The Nazi presentation would pretend to show that the Jews were obviously unwilling to let go of one organizing principle no matter how bad things got, that organizing principle is capitalism. Remember, Nazi is National Socialism. And, Hitler had his own brand of "social justice", to wit, to return to Germans that which had been taken from them by the allegedly reprobate capitalist Jews. Now, imagine this film as a vehicle for advancing Hilter's brand of social justice and national socialism. As a Nazi, one could view this film footage and be permitted to feel satisfaction that the Jews were beyond redemption and meriting extinction in their inherent callous capitalist ways. Such is the original raw film's two fisted Nazi attack on both capitalism and the Jews. Think about it.
