Actually the Memo traffic from Auschwitz constantly complains about the corruption of the dregs of the S.S. sent there as guards. The gold ingots cast from the dental fillings and gold jewelry of the Jews being exterminated consistently went missing. Those tiny gold ingots became a black market currency within the camp, people did everything possible to try to survive, and even the S.S. troopers were willing to be bought, not that it did a lot of good to either side in the long run.
