Just as a matter of interest, were non German minorities much in evidence when the wall was up? I read somewhere that the Allied authorities discouraged immigration to the city, because they envisaged, probably rightly, it would rapidly run out of room.
Im just trying to figure out why, if this is a post wall demographic development, why are they only going into West Berlin? Because that is where the money is?
Ive just been reading Max Hertzbergs series of Stasi novels, and it was interesting to note in the second one there was a rubbish dump in East Germany where all the West Berlin Rubbish was taken. Id never stopped to consider this would be the case, but of course, it all had to go somewhere.
Divided Berlin was much much crazier than that. Underground lines driving from west to west through empty stations in east Berlin, The S-Bahn in all of Berlin was run by the DDR Reichsbahn. With its own railway police force along the tracks. Yes, sworn officials to the DDR enforcing West German law along the tracks. Paid in DM of course, because they were living in the West. And there were more weird entanglements.
