I'm not talking about genetics. There must be something that causes brain damage (and it would probably be a good idea to find it and stop it). The change was too fast for genetics. It was essentially one generstion mostly normal, the next one brain damaged.
I'm talking about all the mid 20th century talk about the "generation gap", "teenage rebellion", and so on. Essentially no stone was left untouched in how the society worked between the "conformist" 50s, and the 70s. Something happened then, or a bit earlier, and it's still doing the damage.
