heh, funny you should bring that up as I grew up in Germany. I hadn't realized the Berufsschule system has become so discarded. But what you point out would (and does) plague a military as well if it wasn't A) a fully-funded state enterprise and B) traditionally required to be large and self-sustaining enough to have jobs that even the duds would be useful at. Needless to say a Google would not be able to squirrel the duds away so easily.
