I really hope for the people that this will bring some solid jobs to the area. I visited Bitterfeld in May, and it's pretty rough in some places. You can tell how many jobs were lost after the wall came down.

So what? East Germany is generally used to refer to the part of Germany formally having part of the German Democratic Republic. Bitterfeld-Wolfen is well in that region.
And, did the poster your replied to say anything otherwise? It is south west of Berlin. Berlin is not the border of East Germany. Well, technically part of it was, but you get the point.
