Most of the creative and ambitious people left the GDR when the wall came down.
I heard a theory recently from someone that was part of the peaceful revolution in Leipzig and now thinks that many people actually didn't mind the government telling them what to do and then not really having a choice in the matter and being under constant surveillance as long as they had a decent life. And that the protests in hindsight probably were more about them seeing how much better the life in the west was than about the personal and political freedom since the GDR apparently did a pretty good job to get rid of those concepts (at least for many citizens).
Now those same people are again voting only for their personal gains and not for freedom for everyone to live however they want as that was never in their interest to begin with
I don't know how you can look at a map clearly showing the aftereffects of decades of communism and blame it on capitalism. Why would east Germany vote fascist due to rampant capitalism but the rest of Germany not do that? I just don't understand.
Maybe what will make you understand, is that 1. the black part is also bad, just a different flavor of it, 2. those two things can be separate issues that are both problematic, not one being right, one being wrong and 3. the DDR was never really communism, like most "communist" countries (like current "communist" China is almost entirely capitalistic)
