JOHANNESBURG — The world, since the 1980s, has become a more unequal place, but South Africa stands out for its stark income disparities. This is according to findings detailed in the first World Inequality Report, which was released this week. The numbers are striking. While capitalism has been the best model to date in lifting people out of poverty, considerably more still needs to be done. – Gareth van Zyl
New research shows unequal impacts of globalization over past 40 years
Report findings identify South Africa as one of the most unequal countries in the world, with the top 10% of earners capturing 66% of the national income.
Economic inequality is widespread and has been growing since the 1980s, calling economic growth policies around the world into question, according to new research from the World Inequality Lab. The study findings are detailed in the first World Inequality Report.
The research relies on the most extensive database on the historical evolution of income and wealth inequality. It aims to contribute to a more informed global democratic debate on economic inequality by bringing the most up-to-date and comprehensive data to the public discussion. The report was coordinated by economists Facundo Alvaredo, Lucas Chancel, Thomas Piketty, Emmanuel Saez and Gabriel Zucman.
Thomas Piketty, coordinator of the report, stressed: “For the first time ever, this report examines how global growth has been shared among individuals in the entire world since the 1980s, with a particular focus on emerging countries where inequality data had previously been sparse or nonexistent.”
The primary research findings indicate that income inequality has increased in nearly all world regions in recent decades, though at different speeds, highlighting the important roles of governments to mitigate inequality. Since 1980, income inequality has increased rapidly in North America, China, India, and Russia, while growing moderately in Europe. However, there are exceptions to this pattern: in the Middle East, sub-Saharan Africa, and Brazil, income inequality has remained relatively stable, at extremely high levels.
Lucas Chancel, general coordinator of the report, emphasized: “The fact that inequality trends vary so greatly among countries, even when countries share similar levels of development, highlights the important role of national policies in shaping inequality. For instance, consider China and India since 1980: China recorded much higher growth rates with significantly lower inequality levels than India. The positive conclusion of the World Inequality Report is that policy matters, a lot.”
The report also reveals the dramatic decline in the net wealth of governments over the past decades and the challenges this poses for tackling inequality. Based on the data, the report discusses promising options to tackle income and wealth inequality—starting with the importance of economic data transparency.
Gabriel Zucman, coordinator of the report, said: “The establishment of a global financial registry to record the ownership of financial assets would deal severe blows to tax evasion and money laundering, and would enhance the effectiveness of progressive taxation, which is an essential tool in reducing economic inequality.”
The report stresses the need for more ambitious policies to democratize access to education and well-paying jobs in rich and emerging countries alike. Public investments in health and environmental protection are also necessary to empower younger generations. To finance these investments in the future, capital taxes on the wealthiest or debt relief have regularly been used by governments throughout history.
Key results of the report include the following:
- South Africa faces some of the worst income inequality in the world, with the top 1% earners capturing 20% of the national income in 2014. Since the end of the Apartheid in 1994, top-income shares have increased considerably. In spite of several reforms targeting the poorest and fighting the segregationist heritage, race is still a key determinant of differences in income levels, educational attainment, job opportunities and wealth.
- Strikingly, since 1980 the richest 1% captured twice as much as the poorest 50% of the world’s population. In other terms, since 1980, 27% of all new income generated worldwide were captured by the richest 1%, while the poorest 50% of the world’s population captured only 13% of total growth. These figures are brought into sharp contrast considering the top 1% currently represents 75 million individuals while the bottom 50% represents 3.7 billion individuals. The population in between, largely comprised of lower- and middle-income earners in North America and Europe, experienced sluggish or even zero income growth rates.
- Since 1980 there have been large shifts in the ownership of capital. Who owns this capital is crucial in determining inequality. Net private capital–the assets of individuals minus their debts–has risen enormously in recent decades, but conversely, net public capital–the assets of governments minus their debts–has declined in nearly all countries since the 1980s due to large scale privatizations and rising public debts. Public capital is now approaching or below zero in rich countries. This exceptional situation by historical standards has strong implications on policy. In particular, it becomes extremely challenging for governments to invest in education, healthcare or environmental protection.
- Wealth inequality among individuals also increased sharply since 1980. Significant increases in top wealth shares have been experienced in China and Russia following their transitions from communism to more capitalist economies. The top 1% wealth share doubled in both China and Russia between 1995 and 2015, from 15% to 30% and from 22% to 43%, respectively.
Emmanuel Saez, coordinator of the report, stressed: “The combination of privatizations and increasing income inequality has fueled the rise of wealth inequality—within countries and at the global level, private capital is increasingly concentrated among a few individuals. This rise was extreme in the U.S., where the share of wealth held by the top 1% rose from 22% in 1980 to 39% in 2014.”
- Global income and wealth inequality will steadily rise if countries continue to follow the same trajectory they have been on since 1980, despite strong growth in emerging countries. By 2050, the share of global wealth held by the world’s 0.1% richest (representing 7.5 million individuals today) be equal to that of the middle class (3 billion individuals).
- However, rising global inequality is not inevitable in the future and limiting it will have tremendous impacts on global poverty eradication. If all countries follow the same inequality trend as Europe since 1980, the incomes of the bottom half of the world population could rise from €3 100 in 2017 to €9 100 in 2050. Alternatively, if countries were to follow the U.S. trend, the incomes of the bottom 50% would rise to just €4 500 by 2050.
The data presented in the report combines in a systematic and transparent manner all available economic data sources, including household surveys, tax receipts, and income and wealth national accounts (including offshore leaks, when available). This enterprise relies on the analysis of more than 175 million data points on inequality.
Facundo Alvaredo, coordinator of the report, said: “This enterprise relies, in one way or another, on the inequality statistics collected in WID.world −The World Wealth and Income Database− since its inception as the World Top Incomes Database in 2011. These databases would not have been possible without the cooperation of more than 100 researchers around the world.”
