Radical constitutional scholarship could make use of a concept of solidarity to enable a new engagement with concepts of welfare and political community. Rather than a welfare state, with all its attendant problems, it is possible to link the concept of solidarity to the notion of a welfare community. A welfare community asserts the importance of common life against capitalist market relationships. Conceiving of the welfare community requires insights from continental philosophy, as well as developments of co-production and core economy thinking. Most importantly, this approach grounds welfare in a political critique of free market capitalism, rather than a theory of rights, and requires a bold assertion of a constitution as a limitation of the socially and economically destructive effects of markets.
