along with fashion, spending lots of money has become "in" again. and spending it on the very items that are contributing to a lot of the world's problems (like war and starvation) will make you famous. in other words, people who do not contribute anything stimulating to the progress of society are today's celebrity... soley for being spoiled brats. in the 80s, it was the likes of princess stephanie of monaco. today, it's paris hilton and the offspring of 80s pop musicians.
there are other details, like crappy pop music and going to church (or being "born again"), but perhaps the most frightening detail of the 80s that is most characteristic of today's world is that an idiot is running shit in the white house. in the 80s it was ronald reagan. the ol' gipper. and today, well, today, you know who it is. back then, the enemy were the russians, and today they are "muslim extremists;" phrases like "high gas prices," "the middle class is dying," and "unemployment is up" are revived; and anti-immigration is a hot issue once again (we gotta beef up the security on those borders!!). basically, it's the same stinky shit, but 2 decades later.
i'm not saying that the 2000s haven't been progressive, it's just that (as the saying goes) it seems as if with every step forward we're taking two steps back at the same time. just to be fair though, there are some things about the 80s that i think have withstood the test of time: legos, chicken nuggets, and apple computers.
