I'm sure those $15,000 bonds imposed on various countries' tourists help an awful lot with that tourism... and the detaining and deporting of tourists also. But it has nothing whatsoever to do with it. Nor does the economy, because everyone is rich, right?
Don't forget the $250 fee per person for EVERY country as well. A family of 5 that wants to go to Disney now spends $1,250 on top of the Disney ticket prices and hotel prices.
Ah, didn't know about that one. Another reason to cross the US of the "visit" list.
