@Facses Long Post:
An interesting rebuttal...
But I think it's based upon the idea of a World Communism more than a World Democracy.
Even in a democracy, those centers of greater CAPITAL are still RICHER...
So, yes, the US would, in theory, still, I think, hold significant sway as a "state" in the same way that larger, more populous states with greater industry (NY, CA before the bust, MASS, TEX and FLA, although they might be slumping a bit now, too, but then these days, who doesn't?) often hold more saw than a Vermont or a Mississippi or a Wyoming and the like.
(Apologies to anyone in those states...nothing against you guys!) :)
Then there's the matter of the US' still-formidable political weight and military presence; since a world police--at least an exclusive one--is NOT one I think will happen for centuries, if EVER, the nation-states would all still have militaries, and a large US military speaks volumes at the table of democracy, the same way that a large corporation tends to have senatorial ears.
(It's both corruption and lobbying, it's just how democracy works.)
So despite your points, I don't think the US would be dstroyed/largely overshadowed as a "state" in this World Nation.
Would it maybe lose some prominance?
Yes...but, really, that's already happening anyway, and we'll get over it--Egypt and Rome and France and Britain and Germany the USSR and all the rest had to, anyway...
@Fasces small post:
How is the American culture so vastly different from Europe's?
Granted, there ARE definite differences, but I get the feeling that most Americans could conceivably walk through London or Paris or Prague or Berlin and--unless they're repulsed by the fact they're Americans because...Bush has caused the world to hate us, basically, or at least made that worse--for the most part get a feel for what life is like there, and not without totally being lost or losing their heads...
Same for most Europeans who might come here--they might have to get used to the fact our football invovles a brown egg we throw rather than kick most of the time and the propensity for people to say "it's the CHRISTIAN thing to do!" and utter prayers and listen to Evangelical blowhards on TV...
But I think most would adapt and learn to like it here, and vice versa.
(And yes, I know I just used like 6 different cliches for Europeans and Americans, all jokes, I'm NOT saying all of one side are like that and vice versa...but really, how would we have THAT big a culture gap?
Most--or at least still about 50%--of Americans, myself included, would be able to trace their history back to Europe a few centuries back, and so it's not as if it's an America/China culture gap, where everything from the letters in the language to the way we eat food to the knowledge of common histories and myths and figures would be a struggle...
USA, Canada, France, England, Germany, Itlay, I GUARANTEE YOU...
We all at least KNOW what the different languages are, and would be able to identify it and get a translator via a book or, in this techno-globalization age, an iPhone or Google app...
We'd know and share a somewhat similar WESTERN background, at least...
Chances are politically we'd have at least a general knowledge...I think most educated Americans could tell you who the Engpish PM is and most educated Europeans could say who teh American President is, and what wars we're in...unless we start a new one by morning, as I write this...only 36 minutes until the 12am, but hey, we've started wars quicker!
And that joke is one both Americans and Europeans would both be able to understand and laugh at as well...
It's not, again, like the East, where allm but the most infamous names are know, and the rest relatively obscure in the West, or at least in my Southern Californian neighborhood...
Ask an American about landmarks and dates and culture points for Europe, and I'd bet an educated American would do well...not ace it, sure, but well enough...
Same for a European--heck, I sometimes get the feeling they might know more about our past leaders and presidents than some who DO live here!
It's still a basic West-to-West culture, and, especially with England, thus traversing the language barrier, I think most Americans would be able to identify with Europeans culturally in more ways than you think, especially younger generations, with increased access to information and the increased exchange of culture across the Web...)
