This research explores the portrayal of social inequality and how social inequality influence the social interactions and dynamics within each social class as depicted in the novel in F. Scott Fitzgerald's iconic novel, The Great Gatsby (1925). Drawing upon Goldmann’s genetic structuralism approach, the study delves into the socio-historical context of the novel to unravel the underlying structures governing characters' behaviors and narrative themes. The analysis identifies four key aspects of social inequality: 1) the American Dream, 2) economic inequality, 3) class distinction, and 4) gender inequality. Each aspect is shown to play a pivotal role in shaping the narrative and providing insights into the complexities of the social fabric of the time. Furthermore, the research examines how these aspects of social inequality influence social interactions and dynamics within each social class. It is revealed that social inequality not only dictates relationships and hierarchies but also perpetuates a cycle of aspiration, disillusionment, and moral decay. The characters' interactions are marked by a constant struggle for recognition, acceptance, and fulfillment within a system that values wealth and status above all else. Overall, this study is expected to offer a comprehensive analysis of social inequality in Fitzgerlad’s The Great Gatsby (1925), shedding light on its sociocultural significance and its enduring relevance in understanding societal dynamics.
