I wanted to respond to a commenter here by linking to an earlier post, but found that I had actually only mentioned this at Half Sigma’s. Anyway, the quote comes from Mark Blyth’s contribution to this seminar on Sheri Berman’s book “The Primacy of Politics: Social Democracy and the Making of Europe’s Twentieth Century”, on page 15:

Indeed, some very interesting paradoxes emerge in this way of thinking [about fascists and social democrats both being mass-based “people’s parties”]. For example, whereas the Nazis taxed capital heavier than workers for the sake of redistribution, the Swedish SAP taxed the workers more heavily than the capitalists. Similarly, while corporatist policy making is seen as quintessentially ‘social democratic’ the true innovators here were the fascist parties. Labor may not have had ‘free collective bargaining’ under such arrangements, but neither did employers have the whip hand. The fact that 95 percent of Germans benefited from Nazi policies shows not just its base of support, but fascism’s essential similarity to the social democratic project of improving the lives of ‘the people’ as a whole.
