What's with the 80's?

I understand how we've got the whole 80's retro thing going on. We've been doing retro for a while now. Did the 50's pretty quick, the 60's almost as quick. The 70's stuck around for a while and now here we are in 2005 acting like it's 1985. And all that I guess everybody knows. The problem that I run into is, even before 1985 we were focused on 1985. 1984 was that distant point in the future and became a classic. The 50's was a time of looking to the future. And for some reason we'd all been thinking there'd be flying cars by the 80's. So what was it about Reagan, Hair Bands, Wall Street, and Crack that we collected around? We stopped talking about the future in fiction by the 80's and started showing what we could already do or what some genius could do that meant it was not far from mainstream like Back to the Future and Wargames. And I guess originality stopped after that cause Grung was punk and then came back the boy bands and Britney and the rest is history, or rather our present. This really doesn't make sense, but come one, does anyone pick up what I'm layin' down?
