enquête menée dans les quartiers populaires de villes burkinabés, Vincent Bonnecase takes as his starting point a study conducted in urban working-class areas of Burkina Faso. He is interested in how much more often "prices" are mentioned in expressions of anger in contemporary societies. In Burkina Faso, cost of living tops the list as a cause of material hardship and feelings of injustice among the working class. The rising prices of consumer goods has stirred often violent protests in Burkina Faso and fueled widespread discontent toward authorities deemed responsible for such prices.
