I think its more that Communism was so bad that they recognized it as an oppressive foreign system, and thus kept their German identity intact, whereas West Germany was just well off enough the Germans forgot who they were. Liberal Democracy is just Communism thinly veiled by the illusion of freedom and private property, but corrupts the Capitalist system to ensure that property is slowly consolidated by the jews, whereas Communism seizes it outright (which in part is why it failed, it was too blatant in its tyranny)
