I'm not sure why you would say that. Here in Europe most people, even the working class, have some understanding of multiple languages.
Here in the german speaking part of switzerland most people, even the grocery store clerk, speak english as well as german. And when you get into the middle class many speak three or more languages (english, german, french, etc).

The u.s. is uniquely mono-lingual.
