Eugenics would still be necessary, because industrialization has wiped out any negative selection pressures on having kids. Famines are history, and no one needs to chop wood to prepare for winter. Any moron can get a job as a janitor and still afford to raise 6 kids at a bare level, but the brainy inventors and CEOs running the place have no time for parenting. If you haven't noticed, eugenics is toxic to the jewish narrative because it affirms hierarchy, and they can only get their multi-racial coalition to work in the absence of hierarchy. Blacks in South Africa or Zimbabwe don't need to appeal to eugenics to kill the whites, it's not even something they could understand. They simply say, "they have stuff that we want!" and fetch the machetes.
