I don't agree with the socialism, but I think there is some truth to the idea that all of us need to bear some responsibility for how the next generation is raised.
Currently too many people worried about "finding happiness" and too few worried about how their actions might affect others.
The "responsibility" was in acting as "responsible" adults.
We don't need to police other people's kids. We need to keep the mature side of life "mature".
There were dirty records, films, comics, jokes, and language back in the 1930s. They were (largely) kept out of the eyes, ears, and hands of kids.
