Marx vs. Nietzsche

I’ve been having fun with Google Ngram Viewer. Here’s my first one. In the dawning, liberal, socialist Culture born after WW2, you can see Nietzsche treading water while Marx takes off in the early 60s, reaching a crescendo in the heady 1970s (when academia began its descent into overt neo-Marxist activism and postmodernism.) But then Marx begins to decline circa 1975 and plummets from 1980 onward, when the Reagan Revolution was taking place, capitalism was booming, and the USSR was beginning to fracture. Nietzsche plateaus around 1996, around the time Generation X cynicism was at its peak.
