This essay investigated the idea of solidarity in a diverse society to move the debate forward from dominant narratives of cohesion and extremism. As such, the author asks if the decline in support for the welfare state is a consequence of increased diversity. Exploring historical and international evidence about the link between diversity and public support for welfare, the report argues that diversity and solidarity are indeed compatible and, rather than seeing growing diversity as a threat to our welfare state, a strong welfare state can in fact create a sense of shared identity and solidarity.
