What does that have to do with right here, right now? Yes, it's an unsustainable system, but it seems to be going strong at the present. I have heard nothing about the next big Russian pop star, but you can bet your sweet ass they know who britney spears is, or whatever crap the kids are listening to these days. Modern colonialism...
Back in the Cold War when Russia was bearing as many weapons as USA you wouldn't know who's the "biggest pop star" in USSR anyway, and they already knew Michael Jackson.
English has taken of as "lingua franca", lab experiments like Esperanto are total failures and eventually we're aiming at "Globbish" within few generations. After all different languages are result of lack of contact between people, a subject that has been taken care of with nowadays communications. Just out of Nationalisms people insist into use impractical and outdated languages.
