They did use to medicate "hysterical women" back in the day.
Yes, I think the fact that life is easier has contributed to this, since it's a lot easier to avoid reality.
My husband and I were just discussing this, as there's a difference in cultures in the north and south of Sweden, since the north gets really cold and people have to face reality or they will die, which is more like how it was in the olden times, even 30 years ago.
I think another factor is that they've been telling kids, for the last 30 years, that everything is relative, and reality is up to me, I can change any part of it.
This is extra evident in how they believe men and women can change and become the other.
When rules and boundaries are removed, when the kids become the rulers instead of the one's being taught reality by adults, they never grow up.
25 year olds are now acting like 5 year olds, because they've never been told that how they're behaving isn't okay.
In fact, like you mention, throwing tantrums have even been celebrated, coddled, and to some extent worshipped. "If I want all the attention I need to be the loudest."
So, they celebrate victimhood, hysteria, and drama.
Posting things like that online also adds to them behaving that way cause now their audience is even bigger, and algorithms promote it, so it's breading even more of it, cause people crave attention.
Nostr might help change this...
