This essay discusses precarization processes with a specific focus on the link between migration and the labor market. It delineates the history of migration in Switzerland and shows how the political regulation of migration is linked to the changing conditions of capitalist accumulation. On the basis of a historical presentation and empirical findings, the article discusses the current political debate on the topic, focusing on the production of “illegal” migration in the context of a repressive migration regime. Finally, two examples of contemporary social movements against this regime are discussed, pointing to the need for solutions beyond state regulation.
