It's a constant discourse in my country to think of today as "dangerous" and idealize some earlier decades where you'd "leave the door open" while by all metrics crime was actually higher.
We just collectively forgot about it.
That's one of the reasons every age and culture has a golden age/arcadia/Eden mythology.
This highlights a great point about past media. Films like The Warriors, Class of 1999, and even A Clockwork Orange play into this notion that juveniles have become worse and worse and we can expect a hellscape from future generations of young people.
Truth, though, is that Gen Zs are so laughably well behaved compared to those my age were that we finally have a period where this genre simply has no place. I hear things from my nephews and nieces about "staying home for the weekend" and think of all the money my sister wasted on a home security system to make sure they don't sneak out and get arrested all the time like we did. Leave that door wide open with soundproofing and they still have no desire to sneak out, especially because nobody else their age is out anyway.
I do agree kids _seem_ to be more risk-averse these days.
Movies seem to be simpler back then. Watched Sleepless in Seattle a while back. I heard it was very popular back in the day. Well … I’m not that impressed, sorry to say. The plot is very simple and a little weird when viewed using today’s social mores. Direction and pacing is adequate. Or maybe I just don’t get it.
I think “things got more complicated” as “information velocity” increased, first with newspapers, then the radio, then TV, and finally the internet - the internet can even be broken down into before ubiquitous social media, before internet video became “trivial”, …
As far as I can tell, books haven't really gotten more (or less) complicated in at least the past 200 years. Or rather: you might be able to detect some trends with a statistical analysis, but the variance is big enough that as a casual reader, you won't notice a trend.
Our youth is usually the part we're nostalgic for and nothing else. You ever hear the nostalgists crying out to go back to a "simpler time"? It's because they were children and the world is simpler for a child that lacks obligations. Fortunately, my childhood was crappy enough and my adulthood fun enough that I can more than let go of the 80s and 90s without any reservations.
