I wasn't a 90s kid, but I always felt like I lived the decade vicariously. Some of the things you guys talked about (kids playing outside, reading, technology not taking over your life) bled into the 2000s. The 90s mentality remained in some form because the 2000s succeeded it. It wasn't until the 2010s that all of that was erased.
Since a lot of these comversations come down to nostalgia and pop culture, I will say that there's been a steady decline in general, and as you get older, you start noticing it more. 90s pop culture was just different. Not all of it is worth having back, but the mentality that created the culture could come back. It's worth a shot.
