This chapter seeks to explain one element of inequality in Western Europe by focusing on the treatment of immigrant communities. It focuses on how attitudes to immigrants – and conceptions of them within a broader framework of social justice – evolved. One of the ways that the ‘long 1968’ challenged European complacency was to present the cause of immigrants as a cause of social justice. By contrast, today immigrants are often depicted as antithetical to social justice. Many commentators have argued that a fundamental tension exists between ethnic diversity and social equality, and depict mass migration as undermining social justice. But where did such ‘welfare chauvinism’ originate from, and how did these ideas entrench themselves within public discourse? In other words, how did we get from social justice for immigrants to immigrants as the antithesis of social justice? A conventional answer to this question might focus on the loss of confidence of left-wing political projects towards the end of the twentieth century, and the concomitant rise of the radical right. This chapter, however, interrogates tensions within social-justice discourses of the left and centre-left, paying attention to emancipatory and exclusionary aspects, and drawing links between the ‘guest worker’ era and the present day.
