A fair point polish bloke. I took note on one Berlin street of 4 cars out of 18 having polish number plates. They are already there but as you say, Germany has yet to open up like here. I think the germans however will be under no pressure to throw the borders open for workers from Poland as they had (in hindsight) their problems with the Turkish guestworkers. Obviously it would be easier for a german speaking pole from Silesia to integrate, sure there's a Silesian Gate in Berlin on the road leading towards Silesia. I still think very interesting times ahead for Berlin, good or bad.
