'I can’t help but recall the story of Monowitz, the for-profit concentration camp the massive German chemicals conglomerate IG Farben built in 1942 four and a half miles from Auschwitz, after its plans to staff a rubber plant with slaves marched in from the camps each morning proved too costly and inefficient to deliver a speedy return on investment. So Farben bought 25,000 slave laborers, many of them children who were cheaper, to build a new camp next to the rubber plant, with even tighter living quarters and more inhumane treatment than the rest of Auschwitz.

At Monowitz, the beatings were so cruel the SS complained to Berlin, the hospitals so crowded that the SS repeatedly asked to build more; Farben refused on account of cost.'
