It sounds like your talking about media for the most part- which yes sorry not sorry but most late 90s early 2000s media IS better then the shit we get today, so many zoomers going back to watch old Ed Edd and Eddy shows, dexters lab, teen titans, KND. All that shit is gold especially my favorite one Static shock.
Now that's all true and good I think the major thing you and a lot of people in this thread realizes is that TIME IS A FLAT CIRCLE and no I'm not memeing. Time is just a constantly moving object that will never stop and never give in. The 90s and 80s where pretty decent for media and as such a lot of people look on the fondly even if things happening in the 90s and 80s weren't GREAT people of the time had nice outlets to get away from the real world. There's a lot of small things like suicide rates in teens being the lowest in US history in the 2000s because shit was simple and things where "just progressive enough" that no one was stressing more then they need to- but this is just a majority meaning there's plenty of 2000s kids who will tell you the 2000s was awful.
I hear a lot that the 50s was good and I'm willing to believe it if only because the 20s was chaos incarnate which would prob leave a lot of people looking fondly at the 50s if they had to put up with the 20s
But also this is only an amarican outlook- and even then.... Again time is a flat circle- the good times can't last forever just like the bad times come and go. You will never experience you childhood again BUT you're childhood self wouldnt be as happy as your adult self as you get married to your sweetheart. Time moves, time flows.
It was the best of times. It was the worst of times. Both are true.
