Parra, what are you trying to proove? That Europe is cheaper than the US? Who cares? As someone who has lived in the US and Europe (Frankfurt, Dusseldorf, and Madrid), I personally do not think Europe is cheaper. First off, taxes in Europe are ridiculously expensive, so the fact that airline tickets, a dinner, and a subway token are cheaper in Europe really does not matter. Hey, how about these comparisons:
2002 Cadillac Seville STS
$48,000 in the US. $85,000 in Denmark
2002 Land Rover Discovery Series II
$37,000 in the US $49,000 in the UK*
2002 Mercedes-Benz E430
$52,000 in the US $60,000 in Germany*
2002 Mercedes-Benz Sprinter van
$24,000 in the US $26,000 in Germany*
In fact, car-wise, only Finland even comes to close to matching what Americans pay.
Some things are cheaper in the US, others are cheaper in Europe, it is that simple. And, don't forget US carriers, with the exception of the NE Corridor, do not compete with railroads. Don't get me wrong, though, I love the US, but love Europe even more, but the cost of living, for my experience, is far more expensive in Europe. A recent survey (actually, not that recent, about a year ago) listed the world's most expensive cities to live in. Just about every major European city was mentioned. Only seven - NYC, LA, San Fran, Miami, Washington, Houston, and Boston - US cities made the list.
