I mean, this claim is not based in reality, it seems to be based in nationalist/sovereignist rhetoric from some French political circles I didn't heard so far. Money flowing into Eastern Germany from the EU was dwarfed by money flowing there from West Germany, in fact the whole EU budget was dwarfed by it. And I saw some effects of that drain on my summer holiday through France and Germany and Austria.
