Where the difference in view might come from, i do care about the people stuck in that horrible system instead of the way it is framed. I dont know what another perspective then "what aid can we offer the people stuck in that situation" really helps anyone but your ego. How anyone can construct an addition schoolyear to learn the language as racism is really beyond me.
It's completely ridiculous and impractical for the state to teach Pashtu to Afghan children in Germany. For English it is almost as bad. Also, learning German does help you learn English, and exposure to different languages does actually make subsequent language learning easier. Multilingualism is not a zero-sum game.
School education is not like a downloadable Database. If it were, it would be more efficient to teach them all the 13 years of stuff at age 18, because that's when they learn fastest. If it were all about usable knowledge (or skills) we should not teach arts, gymn, philosophy or music. Biology and History would also be on the brink for most children.
But it isn't. And yes, it would be nice to help them more specifically, but that's easier said than done. Since we can't recruit a few thousand non-existing experts on the fly, the existing teachers have to deal with it.
