America is a very diverse place when you travel across it, we already have different cultural areas, climates, cities, etc. that use the same money and speak the same language. Already that makes traveling here much more inviting than going to europe, as well as having to get the passport, getting past borderguards, all of that crap. We have vacation spots for all types here anyway, with colorado, california, florida, vegas, there is enough to see here without ever having to go anywhere outside the country.
and most americans now believe europeans hate them and don't want them in their countries. The thought of going somewhere where the people are pissed at your presence and trat you like crap kinda make you not want to go there. We are always given these horror stories about how some unnamed american tourist goes to some country and gets kidnapped and held for ransom, or is taken to cash machines and robbed completely etc. makes people not want to go anywhere.

oh, and it costs a hell of alot more to go anywhere else, traveling, hotels, blah...can travel here for much cheaper.
