Since the 60’s it’s been on a fast downward track.
Screaming nosedive.
I was in high school in the 60s. Girls had to wear skirts, boys could not wear jeans. Kids were polite to the teachers or they’d get in trouble. Kids who drank and were wild got bad reputations. Girls who got pregnant usually went to homes for unwed mothers and came back afterwards having spent the last year “living with their aunt”.
I remember when a divorced woman moved in the neighborhood and I was so curious to know what a divorced woman looked like. Homosexuals? I had never heard of them.
Girls were encouraged to look forward to marriage and children. That was considered normal.
