Freud was wrong about human nature generally, but he had a pretty good grip on the psychology of secular, atheistic modernists like himself.
When I was younger, I found it exceedingly depressing to see so many people dropping out, taking drugs, and "doing their own thing," thinking that they were revolting against custom and convention and everyone over 30, when in fact there was never such a bunch of like-minded conformists in history, all wearing the same clothes, smoking the same dope, and running together like a pack of lemmings headed for a cliff.
Here in the hinterlands, flyover country, the counter-culture really didn't get spooled up until the 70's, not the 60's. Yearbooks from that time period showed everyone looking like Chip from My Three Sons.
The "drug scene" didn't get spooled up here till then, and never really went away.
