Nazi eugenics was a whole-population classification regime, not just sterilization of a few

Evidence

Nazi eugenics - that is, the classification and selection of people on the basis of supposed genetic “value” - was not confined only to sterilization and euthanasia for the “valueless” and the encouragement of fertility for the “valuable”; it laid down criteria of assessment, categories of classification and norms of efficiency that were applicable to the population as a whole. — David Theo Goldberg, John Solomos, A Companion to Racial and Ethnic Studies, 399
