This edited volume studies the complex interrelation of poverty, work, and different stages in the life course, and how it contributes to the permanent existence of poverty and inequality in vulnerable groups in society. Mechanisms of productions and reproduction of these relationships are identified through empirical research carried out in four Latin American countries: Mexico, Argentina, Brazil, and Cuba. This book centers on the experiences of individuals in those less favored social groups who may have suffered structural poverty for decades, or who may have been simply deprived of a basic income to cover their most essential needs.
