When I lived in The Netherlands 99-02, Brussels 02-04, I saw the Euro displace national currencies. Immediately, the price when from about .62 cents US in Dutch Guilders to about 68 cents, the same thing happened in Germany and Belgium - this all happened while a candy bar in the Military PX or Commissary was .45 cents. The Candy Bar priced in Euro's rose to about .84 cents US by the time I left Europe for Israel.
A box cereal in Europe was half the size of those in the US but half the price. Today, the price is equal in Euros/Dollars and the sizes are the same.
Essentially, downsizing US consumer products makes a one-size fit all world or globalized standards. Pricing is nearly equivalent, except that today the Euro fluctuates above the dollar and those Euro Cents over a dollar are the only difference in Price.
If the Euro and USD were equal, then the price would be the same - this is the perfect world where the North American Continent and the EU would be symbolic and thus a true trade zone.
How do we finally get there? The US joins Mexico and Canada in a Trade Zone with a new Currency. This will make all manufacturing within the Trade Zone nearly equal in tax codes, price to manufacture, etc. It will take a continued drop in US living standards, and free education as in Europe to train doctors, fewer lawyers, more medical types and dropouts will contribute their time cleaning toilets. The Doctors will make about 10% more than the rest of society. All will be subsidized for live from the cradle to the grave, and as in Europe where Kings and Queens of Old (with their extended families) will live in luxury on the public dime also subsidized - we will have our diplomats, generals, and political class as in Europe.
The END-game.
Not sure how much of a change that is. Under the G. Washington administration trade negotiations were underway w/ China and Russia, and the first U.S. embassy was set up in Holland to expand trade and borrow money. European money was so welcome in the U.S. that the idea was to us it instead of dollars altogether.
If anything, since then we're less globalized --either that or we could say Europe's become 'Americanized'.
