I’m wondering if any significant number of people were saved by becoming slave laborers as opposed to being gassed in the camps. Obviously one would not then conclude that there was some virtue to this venal activity but it might have been one positive, albeit unintended consequence.
Here’s a link to the column in question.
I certainly couldn’t give any statistics on this one way or another, but ultimately I’m sure most of the slaves were worked to death, so I don’t see much of a benefit, intended or not. A few might have lived through the war who didn’t otherwise, but most were just used and died instead of being killed immediately. I see few positives, even of the unintended variety.
