Forced labor

Hard labor was a fundamental component of the concentration camp system and an aspect in the daily life of prisoners. However, the forced labor deployment was largely determined by external political and economic factors that drove demand for labor. During the first years of the camps, unemployment was high and prisoners were forced to perform economically valueless but strenuous tasks, such as farming on moorland (such as at Esterwegen). Other prisoners had to work on constructing and expanding the camps. In the years before World War II, quarrying and bricklaying for the SS company DEST played a central role in prisoner labor. Despite prisoners' increasing economic importance, conditions declined; prisoners were seen as expendable so each influx of prisoners was followed by increasing death rate.

Private sector cooperation remained marginal to the overall concentration camp system for the first half of the war. After the failure to take Moscow in late 1941, the demand for armaments increased. The WVHA sought out partnerships with private industry and Speer's Armaments Ministry. In September 1942, Himmler and Speer agreed to use prisoners in armaments production and to repair damage from Allied bombing. Local authorities and private companies could hire prisoners at a fixed daily cost. This decision paved the way for the establishment of many subcamps located near workplaces. More workers were obtained through transfers from prisons and forced labor programs, causing the prisoner population to double twice by mid-1944. Subcamps where prisoners did construction work had significantly higher death rates than those that worked in munitions manufacture. By the end of the war, main camps were functioning more and more as transfer stations from which prisoners were redirected to subcamps.

At their peak in 1945, concentration camp prisoners made up 3 per cent of workers in Germany. Historian Marc Buggeln estimates that no more than 1 per cent of the labor for Germany's arms production came from concentration camp prisoners.
