It's not a problem, though? Many people learn other languages in the US/Aus/etc. They just don't get a chance to use them, and those skills fade very quickly.
I'm sure more people would be fluent in another language if daily life motivated retention.
I've studied 3 but only used French for the first time this year in my 40s. I just could never afford to travel until work sent me.
It was inevitable that some language would become the most "global." It's not anyone's fault if it also happens to be their native tongue.
