>>9258598>How much did the Holocaust impact German war effort?
Economically, they were able to squeeze some physical wealth from the victims (gold, jewelry, money, etc.), but not enough to make it worth the expenditure. The slave labor on the other hand was a critical part of the German war industry, but the Jews, Gypsies, and Slavs who toiled away in German factories died at such prodigious rate from overwork or outright murder that the workforce was never able to reach full potential in terms of skill. As a result of this, Allied bombing, diminishing stocks of coal and oil, and to an extent, the over-engineering that went into designing German military hardware, war production was not able to even keep up with the unfree labor system of the Soviet Union, let alone the United States.
WWII was unironically the triumph of the free market and free labor with the United States easily eclipsing production in both quantity and quality over Nazi Germany and the Soviet Union which both relied on a centralized economic model and a vast pool of enslaved populations that had been condemned to toil in concentration camps, gulags, and factories and die by the millions.
Militarily, the Holocaust was a massive waste of men and ammunition who could've otherwise been committed to defending Germany's Eastern and Western frontiers (albeit the soldiers involved in the Holocaust were almost always the the lowest of the low in terms of quality) and at certain times, it created unneeded friction between the Wehrmacht and the SS.
Politically, the Holocaust was an unparalleled disaster that ensured the Nazi ideology would be universally condemned if Germany failed to win the war, which it ultimately could not.
