Mainstream social movement studies have developed a useful kit of concepts and theories, well adapted to understanding social movements in core capitalist countries at the peak of growth of the welfare state. Widespread assumptions about the role of political opportunities, resource mobilization and framing processes need to be updated to make sense of contentious global politics in the 2000s, in particular, adding a focus on the socio-economic conditions for protests. In order to illuminate research results about the social basis of anti-austerity protests, the article critically reviews some recent contributions to political economy. In particular, some of the most influential contributions within Marxist and post-Marxist approaches to relevant capitalist transformations are discussed, with reflections on different temporalities in capitalist transformations.
