Backstopping Social Europe? Welfare-state logic and EU social protection since the EPSR

Debates on European Union (EU) social protection since the European Pillar of Social Rights (EPSR) increasingly focus on the EU's capacity to support national welfare states through coordination, funding, stabilization, and re-insurance-type instruments. This article asks how far classic welfare-state development logics can be meaningfully transposed to the EU, under what conditions, and with what implications for the forms of social protection the EU can plausibly sustain. Drawing on welfare-state formation theory, we use four welfare-state logics as heuristic benchmarks: socio-economic modernization, risk reapportioning, political integration and state-building, and class-political redistribution. The four-logics framework helps clarify why some forms of EU social protection are more plausible and institutionally sustainable than others. It shows that the analogy with national welfare state development travels unevenly. It is strongest where risk pooling, coordination, temporary stabilization, and indirect solidarity are concerned, and weakest where direct EU provision, durable fiscal centralization, supranational social citizenship, or stable redistributive coalitions would be required. The article therefore interprets post-EPSR developments as a constrained expansion of the EU's role in supporting national welfare states under pressure, rather than as steps towards a supranational welfare state. The most plausible trajectory is one of backstopping, re-insurance, coordination, and targeted support and not direct EU-level welfare provision.
