Of course we all understand the moral and ethical horror, I’m simply trying to understand what the Nazi government would be looking at when deciding to continue on with its program of exterminating people.
After huge reversals in Russia and the emanate allied invasion ramping up, why did the Nazi hierarchy continue to allocate man power, money, and resources into the rounding up and slaughter of innocents?
I understand that slave labor was a thing, but (in my understanding) the slave labor output really didn’t justify the expense of building camps and supplying them with officers, security, rations, fuel, administration, and everything else that these camps required. How does this make economic sense?
This question was answered in detail here by the peerless /u/commiespaceinvader. On the one hand, the mass murder of Jews and others was not "rational" but motivated by racial hatred, which was essential to everything the Nazi regime did. It makes no sense to ask whether the allocation of resources was "justified" or "made economic sense" because Nazi ideology mandated the murder of Jews; if it had cost them twice or ten times as much, they would still have continued to do it. On the other hand, since the enslavement and extermination of vast numbers of people also allowed the Nazi regime to allocate huge amounts of unfree labour and steal vast quantities of wealth, their genocidal programme actually turned a profit and helped to sustain the war effort.
