Social Polarization
Overview
Social polarization refers to the phenomenon where the distribution of economic, social, and cultural resources within a society becomes unequal, leading to an extreme widening of the gap between the upper and lower classes. This goes beyond simple income inequality, appearing in all areas of life such as education, housing, healthcare, and information accessibility, reducing social mobility and intensifying class conflict. In the 21st century, globalization, technological innovation, and neoliberal policies have intertwined, making social polarization a global issue. In South Korea, it has rapidly progressed since the 1997 Asian financial crisis, and the country now ranks among OECD nations with high inequality indices.

Economic Polarization
Economic polarization manifests as income and asset inequality. In South Korea, the income of the top 10% is more than 10 times that of the bottom 10%, and the asset gap is even more severe. Soaring real estate prices and the concentration of financial assets are major causes, with housing price increases in Seoul and the capital region particularly accelerating asset polarization. According to Statistics Korea data, as of 2023, the assets of the top 20% are about 60 times those of the bottom 20%. This economic disparity leads to differences in consumption patterns, savings rates, and investment opportunities, reinforcing the cycle of the rich getting richer and the poor getting poorer.
Educational Polarization
Education is a key mechanism that reproduces social polarization. High-income groups secure superior educational opportunities through private tutoring, overseas study, and admission to prestigious universities, while low-income groups become more dependent on public education, widening the educational gap. According to a 2024 report by the Korean Educational Development Institute, the average monthly private education expenditure of the top 20% of households exceeds that of the bottom 20% by more than five times. This leads to inequality in college admissions, resulting in over 20% of freshmen at prestigious universities in Seoul coming from the affluent Gangnam districts. Educational polarization ultimately leads to the inheritance of jobs, income, and social status, making class mobility difficult.
Housing Polarization
Housing polarization appears as spatial segregation and disparities in living environments. High-income groups reside in luxury housing and redevelopment areas, while low-income groups live in dilapidated housing, semi-basements, and gosiwons (cheap study rooms), deepening housing poverty. According to a 2023 survey by the Korea Housing Finance Corporation, the price gap between the top 20% and bottom 20% of housing in Seoul is more than 10 times. Additionally, housing cost burdens pressure low-income households, reducing other consumption, and the quality of the living environment affects health and education. Recently, housing instability among young people has emerged as a social issue, leading to phenomena like "yeonggeul" (mortgaging everything) and "bittu" (borrowing to invest).
Healthcare and Health Polarization
Health inequality is another aspect of social polarization. High-income groups have easier access to quality medical services, health checkups, and nutritional management, while low-income groups often forgo treatment due to medical costs or suffer from chronic diseases. According to a 2024 study by the Korea Institute for Health and Social Affairs, the life expectancy of the bottom 20% income group is 6–7 years shorter than that of the top 20%, and the prevalence of chronic diseases is 1.5 times higher. The COVID-19 pandemic particularly highlighted these disparities, as low-income groups were more exposed to infection and death risks. Medical polarization leads to inequality in survival itself, raising issues of social justice.
Information and Digital Polarization
In the era of digital transformation, disparities in information accessibility are creating new forms of polarization. High-income groups gain an information advantage through the latest devices, high-speed internet, and digital literacy education, while low-income groups and the elderly experience digital exclusion. According to a 2023 survey by the Ministry of Science and ICT, digital information levels were higher among those with higher incomes and younger ages. This leads to discrimination in employment, finance, and administrative services, with the digital divide acting as a factor that deepens social inequality. Particularly, as the non-face-to-face economy expands, digitally excluded groups face a greater risk of being marginalized from economic activities.
Causes of Polarization
The causes of social polarization are diverse. First, globalization and technological innovation have favored high-skilled workers, widening wage gaps. Second, neoliberal policies have promoted capital concentration through deregulation, tax cuts, and labor flexibility. Third, soaring real estate prices and financial market volatility have deepened asset inequality. Fourth, inequality in educational opportunities and the absence of social safety nets hinder class mobility. Additionally, political polarization and ideological conflict make social consensus difficult, slowing efforts to resolve polarization.
Social Impacts of Polarization
Social polarization threatens social cohesion and leads to negative outcomes such as increased crime rates, political extremism, and declining social trust. Economic inequality fosters relative deprivation, heightening social discontent, which can lead to the spread of political populism and extreme ideologies. Furthermore, polarization negatively affects economic growth itself, causing consumption contraction, reduced investment in human capital, and increased costs of social conflict. The World Bank and IMF have published research indicating that excessive inequality hinders economic growth.
Recent Trends
In 2024–2025, social polarization is taking on more complex forms. During the economic recovery after the COVID-19 pandemic, a "K-shaped recovery" emerged, widening the gap between high-income and low-income groups. In particular, the rapid development of artificial intelligence (AI) and automation technology is deepening job polarization. High-skilled occupations collaborate with AI to boost productivity, while low-skilled jobs face the risk of replacement. A 2024 OECD report warned that AI could further lower wages for low-income workers.
Additionally, instability in the real estate market is entrenching asset polarization. From the second half of 2024, expectations of interest rate cuts led to a renewed rise in housing prices, widening the gap between asset-owning and non-homeowning classes. The government has been discussing the expansion of "basic income" and "universal welfare" since 2025, but feasibility remains uncertain due to fiscal sustainability and political consensus challenges.
Meanwhile, digital transformation and the climate crisis are triggering new forms of polarization. Digitally excluded groups are marginalized from non-face-to-face services, and the negative impacts of climate change disproportionately affect low-income groups. In early 2025, the "climate justice" movement spread in Europe and the United States, with growing calls to address environmental inequality. In South Korea, criticism has emerged that carbon neutrality policies increase the energy cost burden on low-income groups.
