Hmm... I don't agree. Immigrants in USA learn English because that's the official language, if they travel to Japan they HAVE to learn Japanese for the same reason...
A simplified communication platform is a HUGE advantage for business, and a common language sets up this kind of platform. It doesn't matter which language is deeper or more interesting, the one backed up by the biggest power will prevail (take a look at Latin by the time of the Roman Republic... it "owned" almost every other languages on the area).
