Latin American legislators, like legislators worldwide, are drawn from a narrow set of elites who are largely out of touch with average citizens. Despite comprising the vast majority of the labor force, working-class people represent a small slice of the legislature. Working Class Inclusion examines how the near exclusion of working-class citizens from legislatures affects citizens' evaluations of government. Combining surveys from across Latin America with novel data on legislators' class backgrounds and experiments from Argentina and Mexico, the book demonstrates voters want more workers in office, and when combined with policy representation, the presence of working-class legislators improves citizens' evaluations of government. Absent policy representation, however, workers are met with distrust and backlash. Chapters show citizens have many opportunities to learn about the presence, or absence, of workers; and the relationship between working-class representation and evaluations of government is strongest among citizens who are aware of legislators' class status.
