How to deal with labor costs

“During the later stages of the war, German industry used slave labor procured from occupied France and Poland, Russian prisoners, and Jewish concentration camp inmates. The living conditions were almost unfathomably harsh: long unpaid hours of work, meager food rations, unheated and inappropriate quarters (for example, dog kennels, stables, bombed work camps), inadequate water, no toilets or sanitation, rampant disease, and no medical attention. The Krupp munitions plants were the primary recipients of this slave labor force. Krupp even built a fuse factory on the grounds of the Auschwitz extermination camp in Poland, in the same area where I.G. Farben built its synthetic coal-oil and rubber plant. ‘Resettled’ Poles and Jews were forced to build the camp itself at Auschwitz (in 1940) but also to work in these adjoining factories until they collapsed from exhaustion; then they were exterminated.” – The World War II Desk Reference, Douglas Brinkley and Michael E.
