Tons of reasons.
- You lived through them. There is a continuity in your mind, rather than a dissociated aesthetic.
- Survivorship bias takes time. We think of bell bottoms for the 60’s, even though there were many other pant styles. Over time, specific things become iconic of an era.
- The internet and mass media flattened and accelerated trends.



I agree with some of your points. I also lived through the 80’s and 90’s and can pick them out more acutely.
But they’re also long ago enough for the survivorship bias to kick in. There are highly specific aesthetics of the 80’s that are regurgitated back to us through media that says “THIS IS THE 80’S”. Think Stranger Things, where they just condensed an entire decade into head nods. Whether or not we personally experienced some of these things, we collectively accept them as “the 80’s”.
Meanwhile, no one is putting Bow Biters forward as iconic of the era, despite the fact that I remember seeing them everywhere when I was a kid. They are not a culturally recognized touch point the way that acid washed jeans and curly mullets are.
I think the average person has a very strong link to the aesthetics of their childhood, too. Someone born in 1995 is going to have a much sharper sense of what the “2000’s” looked and felt like than you or I.
