Am I the only Indian who thinks this is not such a bad thing, prefer one language to unite us all (isn't that the common base for most far-future novels?), don't care which, I can converse in three Indian languages, and know bit of french. In Sweden, all that knowledge is useless, all the main sites are in Swedish, now I am learning å,ö,ä, guess how much fun I am having?
Its not a bad thing if that happens properly. But instead currently we have small number of 'elite' people who always prefer English over native language and we have large number of people we don't know how to read & write English. Since the output(business/knowledge/tech) of this 'elite' group almost always in English and by definition they are in control its not easy for person who don't know English to break loop. Its very easy for the person who know English to get the job compared to who don't. One might say, just learn English and become the 'elite'! Well, learning English is not at all easy for a kid from rural background. This initial barrier dividing among ourselves and now we now have invisible class system based on language. this is apparent if you visit any restaurants/supermarket in cities or just visit city outskirts. My point is process of implementation of single language for all is very difficult.
