ABSTRACT Monique Deveaux’s Poverty, Solidarity, and Poor-Led Social Movements makes a timely, compelling, and important intervention in the philosophical literature on poverty and global justice, and improves our understanding of the nature and extent of responsibilities of variously situated agents towards the poor. Deveaux’s focus on poor-led social movements emphasizes that effective poverty reduction requires building up the collective capacities of the poor to engage in joint collective action to oppose and dismantle unjust structures. This approach politicizes poverty and provides a powerful refutation of some previous approaches that primarily formulated responses to global poverty to consist in mere charity to lighten the poor’s deprivations, or top-down solutions imposed by technocrats and other development experts. Deveaux then extends the concept of solidarity to characterize the political responsibility of the nonpoor, which consists of acting in political solidarity with poor-led organizations and movements. It is this latter move to extend the concept of solidarity to characterize poor-nonpoor cooperative activities that I question in this commentary. When the concept of solidarity, understood as identification-based joint action, is stretched to encompass cooperation between all those who may act together to resist, oppose, and dismantle the structures of domination and oppression that constitute poverty, there is the danger of obscuring the alienation and oppositional social positions that attend conditions of structural injustice. To acknowledge the limits and dilemmas of solidarity practices between the poor and nonpoor is perhaps a sober reminder of one of the major costs of living in conditions of structural injustice.
