"sources of social problems".

Was talking to my son about MKUltra, and Ted came up, so I pulled up an early 90s manually printed copy of Industrial Society and It's Future.

It had tween (early teen at best) Gary's notes in the margins, which were the most interesting bits to me, for nostalgia reasons.

Amazingly, the first margin note was "this is where he starts becoming a nut. I start to disagree with almost everything after this point." It was partway through the section "sources of social problems".
