Its central goal is to assess the impact of variation in working-class representation on citizens’ perceptions of democratic health and satisfaction. The proposed causal link is complex yet coherent: in contexts where workers are underrepresented in public institutions—specifically, in Latin American nations—voters recognize this deficiency, express concern about the lack of worker-centered policies and tend to feel more dissatisfied with the political regime.
