That's also when sex Ed started, contraceptives became exponentially more common, television became ubiquitous, youth had exponentially more drugs illegal and legal pushed on them, and heavy metal poisoning reached it's historical peak. The deleterious effects of such influences are objectively measurable and irrefutable.
Heavy metal poisoning explains the larger part of all boomer negative behaviors by the way, they're the most lead poisoned generation in recorded history and early life lead exposure has well documented and consistent psychological effects.
So however far you go back, you simply have to stop the 1960s from happening, because that's where America was locked in to the current result of collapse. Europe was locked in to a path of collapse and genocide since world war one at the absolute latest, that was irrecoverable without a total collapse and reset, Europe was always going to die after WW1.
