In quite a few countries other than America (such as in Europe and Asia, etc.), knowing two or even three languages fluently is commonplace. Americans are relatively backward in that regard, I'll admit.

The average American can draw a 500-mile-diameter circle centered on his home and most likely he fluently speaks the predominant local language everywhere in that circle.

The average European, not so much.

I think you would have to admit, Europeans are obviously more than a little backward in that regard, Asians? They are even worse if you consider say China, where you move from place to place and the Chinese do not even speak each other's Chinese
