Human rights encompass the fundamental entitlements that every individual should possess regardless of their background. Sociologically, the struggle for women's rights, racial equality, and LGBT advocacy are all central to the broader movement for social justice and the protection of human dignity. These issues address systemic inequalities and the need for inclusive social policies, making all of them critical components of human rights discourse.

In sociological terms, subordinate groups are those that hold less power, resources, and social status compared to the dominant group. Conflict theory suggests that social problems frequently stem from the systemic inequality and exploitation directed by dominant groups toward these marginalized populations.

Technological stratification manifests through the digital divide, which is the unequal access to information and communication technologies, and the knowledge gap, which refers to the disparity in information processing and utilization skills. Both phenomena create inequalities in how different social groups benefit from technological progress.

Intersectionality is a theoretical framework, popularized by Kimberlé Crenshaw, that highlights how different social identities are not additive but interactive. It explains how individuals experience unique modes of discrimination and privilege based on the combination of their social categories. This approach is essential for understanding how systemic inequalities, such as poverty and marginalization, are shaped by the intersection of race, gender, class, and other identity markers.

Intersectionality theory posits that various social categories, such as race, class, gender, and other forms of identity, are interconnected and cannot be examined in isolation. These overlapping systems of social stratification create unique experiences of discrimination or privilege. By considering all these factors, sociologists can better understand how power dynamics operate across different social groups.

World-systems theory, developed by Immanuel Wallerstein, categorizes countries based on their economic and political power. Core nations are dominant, while peripheral nations are exploited. Semi-peripheral nations, such as Brazil, occupy an intermediate position, exhibiting both core and peripheral characteristics. They are often industrializing and possess significant regional influence, yet they remain dependent on core nations for capital and technology, reflecting a complex position within the global capitalist hierarchy.

The term 'Second World' historically referred to the communist-socialist industrial states, primarily the Soviet Union and its satellite states in the Eastern Bloc. These nations were characterized by state-controlled, centrally planned economies, distinguishing them from the capitalist 'First World' and the developing 'Third World'.

Modernization theory and dependency theory represent the two primary frameworks for analyzing global inequality. Modernization theory suggests that nations develop through internal technological and cultural changes, while dependency theory argues that global poverty is a result of the exploitation of peripheral nations by core nations. Together, these theories provide a comprehensive, albeit contrasting, understanding of how wealth and power are distributed on a global scale.

High-income nations, often referred to as the Global North or core countries, control a disproportionate share of global economic resources. Estimates consistently show that these nations account for approximately 75% of the world's annual wealth output. This concentration of wealth is a result of historical industrialization, technological dominance, and favorable trade positions, which perpetuate global economic inequality between high-income and low-income nations.

Global economic inequality refers to the disparities in wealth, income, and resources between different nations. This perspective examines how the global economic system creates advantages for some countries while leaving others in states of underdevelopment or poverty, focusing on the macro-level gaps between the Global North and the Global South.
