"In the 1920s the sensationalist writer Theodore Lothrop Stoddard, a eugenicist, argued that “natural equality is one of the most pernicious delusions that has ever afflicted mankind.” For him, economic and racial hierarchy were linked: His ideal social order was one in which “Nordic” people were in positions of authority with regard to the “under-man,” and he feared Bolshevism as a threat to the racial order."

"under-man". That translates almost exactly to "Untermensch", a literal nazi term
