Legit though, nobody alive today had anything to do with English becoming the trade language. It used to be French, but that went away and English filled in.
Any country where English is the primary language is going to have less people needing a second language for anything other than the general benefits it brings, which aren't truly necessary.
It isn't like everyone, everywhere speaks English on top of their first language, nor does everyone speak multiple languages. They do just fine with the dominant language of their country, and there's nothing wrong with that.
Also, Australians don't speak English. They speak Cunt :)
