The Limitations of GDP: Why Should We Look Beyond It? Gross Domestic Product (GDP) is currently the most widely used indicator for evaluating national economies. However, more than 80 years after its formal introduction in the 1940s, modern society faces complex and multidimensional challenges. The concept of GDP was developed by Simon Kuznets during the Great Depression in the 1930s and became a key tool for measuring national economic scale after being internationally standardized following World War II. While GDP excels at simply illustrating a nation's economic size, there is growing criticism that it has clear limitations in evaluating the quality of life for its citizens or the comprehensive development of society. Recently, Nobel laureate in economics Joseph Stiglitz raised these issues in a column published in Project Syndicate, emphasizing the need for new development indicators. Stiglitz points out several key limitations of GDP. First, GDP merely measures the sum of economic output without considering how that production impacts people's lives. He notes, "GDP tells us how much a country produces, but it doesn't tell us for whom it is produced, or at what cost." For example, an increase in GDP does not necessarily mean an improvement in the living standards of all citizens. If income inequality becomes severe, most people may not feel the benefits even if GDP rises. Indeed, in the United States, GDP has grown continuously since the 1970s, but the real wages of the middle class have largely stagnated. Furthermore, GDP does not measure or reflect negative factors such as environmental degradation or resource depletion. Paradoxically, activities like environmental cleanup or natural disaster recovery are considered economic activities and contribute to GDP growth. Stiglitz criticizes this, stating, "If you cut down and sell forests, GDP increases, but the resulting ecological destruction and loss for future generations are not accounted for at all." Sustainability is a particularly crucial issue in modern society. Stiglitz points out, "If we fail to address issues like climate change and resource depletion, current economic growth will only leave a greater burden on future generations." If economic growth does not simultaneously harmonize with the environment, it could be considered a regression in the long run. According to the Global Risks Report published by the World Economic Forum (WEF) in 2025, climate change and environmental crises were identified as the most severe risks threatening the economic outlook over the next decade. The report listed extreme weather events, biodiversity loss, and natural resource crises among the top five risks. This is precisely why GDP cannot adequately explain these crisis situations. When a country extracts and exports large quantities of fossil fuels, its GDP increases, but the resulting carbon emissions and climate crisis costs are excluded from GDP calculations. To address these issues, Stiglitz proposes new multidimensional indicators. His observation, "What we measure is what we manage. If we measure the wrong things, we will strive for the wrong things," vividly illustrates the importance of development indicators. Through indicators that encompass various factors such as health, education, environment, and income inequality, we can pursue qualitative growth, moving beyond mere quantitative growth. The 'Better Life Index,' developed by the OECD in 2011, can be seen as a good example of such an endeavor. This index comprehensively assesses 11 areas: Housing, Income, Jobs, Community, Education, Environment, Civic Engagement, Health, Life Satisfaction, Safety, and Work-Life Balance. Each area includes both objective indicators and subjective satisfaction levels to measure the quality of life for citizens in a multidimensional way. The Complexity of Modern Society and the Need for New Indicators In 2019, New Zealand became the first country in the world to introduce a 'Wellbeing Budget,' prioritizing the improvement of citizens' well-being over GDP growth as its primary policy objective. Then-Prime Minister Jacinda Ardern declared, "Success is no longer measured solely by GDP. Whether New Zealanders are living better lives is the true measure of success." Iceland and Scotland have also adopted similar well-being economic models, and Bhutan has used Gross National Happiness (GNH) instead of GDP as its national development indicator since the 1970s. These countries comprehensively consider environmental protection, cultural preservation, and mental well-being when making economic policy decisions. So, what about the situation in South Korea? For decades, South Korea has prioritized GDP growth as its foremost national policy objective. As a result, it achieved remarkable economic growth, transforming from one of the world's poorest countries in the 1960s to joining the ranks of developed nations in the 2020s. However, this process also exacerbated serious social
