Radical right-wing politics is commonly understood as a cry of the “left behind” - working-class voters who lost out in the transition to a post-industrial, services-based, and globalized economy. Philip Rathgeb, a political economist at the University of Edinburgh, challenges this view in How the Radical Right Has Changed Capitalism and Welfare in Europe and the USA (Oxford University Press, 2024). Rathgeb joins Chris Maisano on the latest episode of the SLU podcast Reinventing Solidarity to talk about his book, what differentiates the Republican Party from its right-wing counterparts elsewhere, and how his research might inform the efforts of people working to reinvent solidarity in the current moment.
