MMm! In the limited experience I have had in a few trips to German industrial factories, a lot of German factory workers are not German! Mind you I suppose that could be said for over in the UK as well.
I'm very proud of the British engineering we have left over here, but I must admit I do admire the way the Germans re invest in their manufacturing. I suppose that's a good job as I work for them, strangely no sign yet of them not selling their cars, lorries and guns over here yet.
