Are North Americans the least hospitable people?

Some cultures have hospitality commanded by their very [i] religion[/i] (none of which dominate N. American culture). Others are simply hospitable from secular values, and manage to do so better than Westerners. Europe and Latin America are Western, but I think North America comes in dead last.

Edit: perhaps I should have explained that hospitality isn't the same as niceness, firendliness, courtesy, "good experiences" or how much capital an entire country donates to another
