Among EU governments and political parties, there is a rising tendency to claim that intra-EU migration puts a serious strain on the sustainability of welfare provision. Several countries are enforcing measures aimed at limiting the access of other EU citizens to unemployment schemes, health care assistance, etc., and also calling on the EU to tighten rules to end "benefit tourism". However, Commission reports have shown how minimal the impact of "benefit tourism" is on welfare scheme budgets. Does this political attitude, which exposes the growing concerns of the traditional parties about the competition of right wing populism, risk adding further barriers to labour mobility and to the portability of rights, especially in a time of widening gaps in employment differentials? How much of the welfare financing difficulties do the intra-EU flows account for? Does this identitarian rhetoric add up to a race to the bottom in social provisions? Should a European response, in defence of the single market, aim to establish a level playing field rather than accommodating social competition?
