The management of these camps was a complicated and confusing business. Army authorities, private enterprises, and the SS tried to enrich themselves by making use of the Jewish labor supply from Eastern Europe and the – very small – number of Jews supplied from Western and Southern Europe who were selected as eligible for work. Straight through this story of exploitation of cheap labor living in miserable conditions runs the leitmotif of the firm determination of Himmler’s SS to obey Hitler’s order to exterminate the Jews.  The result was that the number of places for forced labor for Jews decreased steadily and that Jewish workers were deployed especially in Arbeitskommandos for industry in concentration camps.
