Don't you know what you are talking about? Guy, help me a little here. Arguing that the Americans are better because they have achieved a single nation while the European haven't?
To repeat what Winger said? "Our forefathers have been kicked out of every decent country in the world"?
I do not think Leauki is arguing Americans are better (in many respects Canada is a kissing cousin to America, except it never assimilated Quebec, while Louisiana was assimilated), except at nation building. Let's take a look at 3 countries - basically all in the same boat.
Canada never had a civil war, but perhaps that would have been better. They have had a problem since France was kicked out of the new world, and that is Quebec. hardly a model for the Europeans to follow as they want something that can unify them, not have them remain as they are today. Canada is very similar to where Europe will be in 20 years, but that is not the end of their Journey.
Mexico is like Canada and the US in many respects. But in one, they are woefully behind. Like Europe, they are saddled with Classes - real classes, not made up ones for political purposes. And that has stymied their development into a first world country (they have all the gifts of the US, except a constitution that says all men are equal and the belief in that doctrine). Mexico is where Europe does not and cannot go. So where is Europe going to look for hope in maintaining its position as a world power (as that has dwindled with the ascendancy of the Asian countries)?
America. Yea, America has a lot of problems, many worse than other places. But it is a work in progress, and Europe figures they can either adapt or die (actually just become irrelevant, which is as bad as death to the ego).
To get back to the natural borders, 3 countries with almost identical natural assets. Yet one is at the top of the heap, and the other 2 are not. back in the 18th century the populations of Canada and America were not that different. But America grew through immigration (lots and lots of it). Why?
being a native born citizen, I cannot really answer other than with opinion. But I do listen to friends who were not born here, but chose to make a life here. Hope. America offers hope. is there racism? yes, but not on every street corner. if it bleeds, it leads makes great headlines, but does not really tell you the story of every day life in the US. Millions of minorities will go years, and some even a life time, and never worry about being called a name, beat up, shot, stabbed, or in any way discriminated against. You will never hear those stories. They do not bleed. And so they go quietly about their lives, assimilating, and living free. They want to be American, because it means more to them than an accident of birth. it represents an ideal. An ideal that has not been duplicated elsewhere.
So yes, in that respect, America is better, and Europe knows it. it is what Europe wants to be, and may be someday. As you say, they have 1000 years of history to over come. But America was not born from the garden of Eden. The bloodiest war of all time for one nation (as a percent of the population) was the American Civil War. Perhaps we just did it all at once, as Leauki says, instead of inflicting it by a thousand cuts, as Europe did.
