I’d actually guess that there were similar percentages of 18-24 year olds with similar views in the 60s and 70s. Maybe slightly less given that back then you were expected to actually graduate from HS at 18 or college at 21, and fewer actually went to college. But it’s easy to be “anti capitalist” for a man-child or woman-child that is still dependent on mommy and daddy.
