It's well known that the Nazis cared a lot about the genetic health of the population they controlled, and that isn't just limited to race. The Nazis had plenty of eugenic policies — I believe German "anti-socials" (alcoholics and homeless people) were the first to be forcibly sterilized and sent to concentration camps. However, the Nazis were ostensibly committed to National Socialism. So there was an egalitarian component to their message as well. A major component to this was finding a middle path in modernity between liberalism/capitalism and communism/international socialism. Therefore, the Nazis believed in government projects, and rejected laissez-faire policies. However, laissez-faire policies were typically the ones most associated with social Darwinism; "If you don't help the poor, they will cease to exist" was basically the thinking. So how did the Nazis make a coherent message/policy that allowed for their social Darwinist/eugenic principles to persist but also get the government more involved in the economy?
