But the strangest thing is that you don't need to be of a certain ethnicity to speak multiple languages. Sure, I think it's less likely for some average US-born employee, but I would still guess that probably >10% have got to speak a foreign language, especially since they're all highly educated people who had more exposure to other languages and cultures than the average American.
