From Resource to Burden: Rescaling Solidarity with Strangers in the Single Market.

'Organised solidarity' of a mediated legal form constitutes the backbone of the modern welfare state built on solidarity between strangers. The interplay between the single market and the national social systems is key in defining who owes what to whom under the 'transnationalised' European solidarity. Free movement rights have increased the 'entanglement' of national social systems' revenue and expenditure sides, considered to jeopardise their steering capacity. As a corollary to free movement, transnational solidarity does not take place beyond or between national welfare states, but rather within: as solidarity with strangers. Here transnational solidarity is applied by way of a sociological framework to trace the evolutionary path of free movement of persons as it fluctuates between 'ommodification' and 'decommodification'. Against that backdrop, this article reviews whether a paradigm shift is currently promoted as to the question where solidarity with strangers begins and ends.
