Book excerpt: Struggles for Justice in Canada and Mexico examines Canadian and Mexican communities engaged in collective action to address problems related to the context of aggressive capitalism, which favours economic freedom of the powerful over the needs of people and the planet. The book’s several case examples portray income-generating projects; action to promote health, adequate housing, and a safe environment (including resistance to mining); women’s resource and advocacy programs; as well as grassroots support organizations and independent organizers. The author gathered stories in six states in the south of Mexico and two provinces in Canada between 2004 and 2010, with follow-up to 2012. Thematically, they centre on oppression and struggles for rights experienced by the poor, women, and Indigenous peoples. The author’s case-study method bolsters her narratives by including interviews, observation, and some participant-observation, with analysis that draws on social movement theory from sociology and community organizing theory from social work as well as knowledge from social psychology, liberation theology, popular education, and political science. The book presents the common themes and illustrates the central theories for practitioners in the many fields that promote social justice: social work, social development, health, human rights, environmental protection, and faith-based justice movements, among others. The conclusion presents a framework for conceptualizing social justice practice as a congruent paradigm composed of values, theory, objectives, and practice methods.
