The “Three Tiers of Inequality Theory”, a thorough theory that looks at the intricacies of inequality in modern countries, especially in the wake of the COVID-19 pandemic, is introduced in this chapter. According to the thesis, there are three interconnected levels of inequality: individual, cultural, and structural. Institutional factors that produce differences in access to resources, such as political and economic institutions, are referred to as structural inequality. While individual inequality studies how individual characteristics like gender, race, and socioeconomic status exacerbate disadvantages, cultural inequality focuses on cultural behaviours and ideas that uphold social hierarchies. In order to alleviate inequity, the chapter also incorporates classical Chinese philosophy, particularly the idea of “Tianshi Dili Renhe”, which emphasizes the significance of time, place, and interpersonal relationships. The chapter offers a multifaceted approach to comprehending how these inequalities interact and deteriorate, particularly during crises like the pandemic, by combining both contemporary sociological ideas and traditional wisdom. The Three Tiers of Inequality Theory provides useful guidance for addressing inequality through all-encompassing, systemic strategies that give priority to structural changes, cultural transformations, and group human activity. Ultimately, this framework advocates for a holistic approach to social justice, aiming to reduce inequalities and foster a more inclusive society.
