Uhm...it's called Westernization and the majority of the world uses English in terms of the economy. Also consider the fact that though people may hate the US, but if given the chance, they would live there. Kinda odd, but that's my opinion.
I can assure you, Flavius, that here is one who would NOT!!!
Yes, that is because you have no need to or for whatever preference. However, let's say you asked a population of refugees or a third-world population. Obviously, the majority of them would prefer moving to the US because they know that conditions there are much better and most importantly, a better chance of survival. Generosity also happens to improve image too ya know.
