Have you had a chance to study what is called "The Civil War"?

The Price in Blood! Casualties in the Civil WarAt least 618,000 Americans died in the Civil War, and some experts say the toll reached 700,000. The number that is most often quoted is 620,000. At any rate, these casualties exceed the nation's loss in all its other wars, from the Revolution through Vietnam.
The Union armies had from 2,500,000 to 2,750,000 men. Their losses, by the best estimates:
Battle deaths: 110,070
Disease, etc.: 250,152
Total 360,222
The Confederate strength, known less accurately because of missing records, was from 750,000 to 1,250,000. Its estimated losses:
Battle deaths: 94,000
Disease, etc.: 164,000
Total 258,000
Apparently you've never heard of the US Civil War.
No reasons are jealousy or envy, at least not in Europe.
Having had the experience of living in Europe as well as the US, I'd have to say that this is simply untrue. I've had countless Europeans assume that because I was an American I was much wealthier than they were - one incident that specifically stands out in my mind was when I went to buy a leather coat in Firenze and the very first coat I tried on in one store was just the design I liked and a perfect fit.
A group of young Italians immediately began whispering about how I was a typical American - here they were carefully looking, trying to shop on a budget and an American just waltzes in and buys the most expensive coat five seconds after he arrives!
Of course, the coat cost half of what I would have expected to pay in the US - I have many, many similar anecdotes, all of which involve Europeans assuming that I am some kind of millionaire, which I certainly am not.
There is clearly an envy factor involved. The standard of living in France, Spain and Italy is far below what most American suburbanites are accustomed to, and in Germany and Switzerland the standard US amenities are available, but are considerably more expensive.
Using your stated source of data, the CIA Factbook, the main European nations have an average spending power per citizen of between 52% (Spain) and 85% (Switzerland) of an American. This indicates that the average American has something like 30-50% more disposable income than the average European.
If Europeans are concerned about their economies (which they certainly are) and Americans appear to be so much better off, envy is quite natural.
And the fact that you are a European makes you less qualified to assess whether Europeans are envious or not.
Americans can certainly be arrogant - but Europeans are not immune to that vice. Americans can certainly be meddlesome, but this is also a vice which Europeans have been known to indulge in.
At the same time, Americans are also willing to accept the vast responsibilities those positions entail.
You Germans would also know a lot about that.
Obviously you don't speak for Europe.
The anti-Americanism within Europe is clearly connected to jealousy about America’s position, worry about American culture dominating European culture and also because America is the world's only superpower.
European socialists not only hate capitalism but hate the most successful capitalist nation in history, America and envy the higher standard of living and affluence this has given America.
What really frustrates the current crop of European leaders, isn't Bush himself, "but what he stands for: a powerful United States, to whom they are beholden for their very existence."
"Not only did we save Europe from Adolph Hitler, paying in American lives to liberate much of the Continent, but we spent trillions of dollars protecting Western Europe from a Soviet takeover after the War. But somewhere along the line -- after the Marshall Plan rebuilt Europe and the Berlin airlift saved the western half of the city from the same fate as its eastern sector -- European leaders began to resent the United States, big time."
This is clearly envy and jealousy.
