Are you really sure about that? Southern Europe is not Germany, it doesn't have that famous high quality universal healthcare. Not even countries such as Italy are able to guarantee consistent quality - what you get in southern Italy will resemble Mexico or Thailand much more than Germany. Real estate costs a lot there compared to the US, and finding well paid work (or any work at all) is much harder. Anything you heard about EU public transit mostly doesn't apply in the south, you will need a car; but the roads aren't prepared for today's amount of traffic, and there's not enough money for maintenance nor construction.
