This chapter presents the book's premise and lays the groundwork for a thorough examination of the different types of inequality. It starts by looking at inequality in a larger perspective and highlighting how social elements that contribute to inequalities are interconnected. Instead of being the cause of these inequalities, the COVID-19 pandemic is viewed as a magnifier that has revealed underlying systemic problems that have varying effects on various socioeconomic groups. The chapter emphasizes the differences between invisible, visible, and ignored inequality and calls for a thorough investigation of how these problems appear in day-to-day existence. The book's conclusion emphasizes the significance of taking action after introspection, arguing for inclusive solutions, changes to legislation, and a shared obligation to overcome these inequalities. This chapter sets the stage for the book's analysis of 101 distinct inequalities by offering case studies, frameworks, and theoretical ideas. Each of these inequalities illuminates important problems and possible remedies. The intention is to stimulate an international discussion on how to create societies that are more just and equal.
