It probably doesn't mention the "red vienna", because "the last 80 years of progressive politics" have not much to do with the idea-producing that went on before? "Red vienna" is a byproduct of that cultural climate prior to 1914. After World War 2 there might have been some isolated blurbs of Vienna's former greatness but even those are just the crumbs of what collectivism and anti-semitism started to grind down before Hitler undid it completely (and long lastingly) when he marched into his home country.
