English comes by its huge network advantages honestly. All four of my grandparents were born in the United States, but three were born in households in which a non-English languages was spoken, and two were educated entirely in another language (German). Everybody learned English, and that was no big deal. The majority of Americans have ancestors who didn't speak English before they arrived in America. English is by no means perfect, but it is pragmatic, as Jeff says.
