Organizational Forms and Welfare Coalitions: Corporate Law and the Movement for Social Insurance in the US and UK

Scholars of the welfare state have long argued that, in liberal democracies, welfare state expansion depends on successful coalitions in its favour. Under what circumstances do these coalitions form? Party systems, economic interest, and political mobilisation have all been thought to influence the emergence of coalitions for welfare state expansion. In this article, I argue that law plays a critical role in facilitating the last of these factors. Drawing on a growing body of literature that sees law as constitutive of, rather than merely reflective of, social relations, I demonstrate that available legal forms meaningfully inform opportunities for welfare coalitions. In particular, I examine how debates over what a trade union is-a voluntary association of individuals, or a corporate body deserving of a state statute-shaped coalitions for welfare reform in the US and the UK at the turn of the twentieth century.
