Of course, the 80's to me was all about punk rock (which was actually a late 70's thing for me in the beginning).
I don't remember the 90's and it's better than way, Decade of Turmoil is what I call it. But, materialism was the social definer.
The millennium decade I DO remember.
But, I think the economic problems are what is going to define it and the return of crafting/hand-made culture will have a sociological impact on the future.
