I was unclear, I suppose. I did not mean to conflate but to compare Wader and Biermann. Does a West German anti-capitalist have more in common with an East German anti-socialist, or with the socialists in power in the East? I think there is something in the performance itself, rather than the content of the particular song, that matters.

I think that what both performers are doing is defying in an act, and that they are essentially arguing against the system in place rather than for any specific alternative (Wader was too smart to miss the failings of the East; Biermann was not promoting American capitalism).
