The Role of Education in Mitigating Income Inequality: A Conceptual Framework

Income inequality remains a critical global challenge, marked by widening gaps between the rich and the poor within and across countries. Its socio-economic consequences—such as reduced social mobility, deepening poverty, and increased political instability—pose significant barriers to sustainable development. Education is widely recognized as a key lever for mitigating income inequality by enhancing skills, productivity, and upward mobility. However, persistent disparities in access to quality education often reinforce existing socio-economic divides, limiting education’s equalizing potential. This study examines the complex relationship between education and income inequality, emphasizing the mechanisms through which equitable access to quality education can reduce income disparities. A notable aspect of this research is its use of Scopus AI to conduct a comprehensive and systematic review of academic literature, policy documents, and international case studies. Drawing on this review, the article proposes a conceptual framework that identifies critical factors—such as educational quality, socio-economic barriers, labor market integration, and policy interventions—that shape the effectiveness of education in narrowing the income gap. By addressing underexplored dimensions of this issue, the study underscores the need for inclusive education systems and targeted policy reforms to leverage education as a sustainable pathway toward greater economic equality. The paper concludes with context-specific policy recommendations and highlights avenues for future research to inform more effective strategies for combating income inequality through educational advancement.
