Yeah, and 9 of the Top 10 most visited places in the entire world are in the U.S. I guess people all over the world do care about the U.S., don't they?
Again, facetious claims and you probably know it. They are the
attractions, not places. The sort of things people take their kids etc, so the attendees are likely to be in groups of 4 or more for the most part. Of course tons of people see Times Square etc. (actually, you inflated your claim of 9 out of 10 regardless - only 6 of the top 10 are in the USA*)
What
actually matters in terms of popularity of tourist destinations is how many people from elsewhere - i.e. another country - would travel there. America is well travelled but hardly 9/10 of the the must-see places by any cultured standard. You'd have to be a cultura philistine to desire to see Las Vegas over The Great Wall of China, or Disney Land over Great Barrier Reef.
Anyway, America is far from being the top tourist destination worldwide... France beats it by over 17 million people.
1 France - 76.80 million
2 United States - 59.75 million
3 China - 55.67 million
4 Spain - 52.68 million
5 Italy - 43.63 million
6 United Kingdom - 28.13 million
7 Turkey - 27.00 million
8 Germany - 26.88 million
9 Malaysia - 24.58 million
10 Mexico - 22.40 million
