Plus, I hear your point about pragmatics, but I am also appreciative of the exercise of learning the language as part of expanding ones horizons. "Walk a mile in his shoes" kind of deal, which only gets lip service unless one has actually needed to switch mental, cultural and linguistic contexts.
I also honestly think that more Americans are not bilingual (or perhaps even interested in such a thing) because of the lack of opportunity to use that skill.
