In this subject we examine the challenges of creating a more equitable social world by aiming to understand social inequalities and their causes and consequences from a sociological perspective. We critically examine patterns of inequality within Australia and in global contexts, and explore the ways in which these patterns are rendered invisible or visible. Explanations of different kinds of social inequalities are examined within the context of theories of social stratification, power, equity and social justice. We tackle contemporary challenges such as the growing gap between poverty and wealth, gender inequality, racial discrimination, barriers to civic participation, alienation, class conflicts, and inequalities in the world stratification system. Students engage in critical thinking about the ways sociological theory and practice can contribute to effective polices and their implementation for shaping a more equitable social world.
