East Germans got fucked by annexation.
Not quite that one-sided. Yes there were plenty of cases where the west had their noses in the air. At the same time, for example, the west poured a large amount of money into rebuilding and bringing the east back up to the modern standards - see the Solidaritätszuschlag.
Also, interesting how you first try to discredit the idea that there is any overlap between people wanting the DDR back and fascist supporters, and then suddenly have a whole bunch of excuses as to why those people there support fascists.
