"We live in a system where resources extracted from labor and nature in low-income countries continue to sustain the prosperity and the unsustainable lifestyle of people in high-income economies and rich elites across countries. These patterns are not accidents of markets. They reject the legacy of history and the functioning of institutions, regulations, and policies—all of which are related to unequal power relations that have yet to be rebalanced."Jayati Ghosh"History, experiences across countries, and theory all show that today's extreme inequality is not inevitable. Progressive taxation, strong social investment, fair labor standards, and democratic institutions have narrowed gaps in the past—and can do so again. The World Inequality Report 2026 provides the empirical foundation and intellectual framework for what can be done."Joseph E. Stiglitz"Inequality is silent until it becomes scandalous. This report gives voice to inequality—and to the billions of people whose opportunities are frustrated by today's unequal social and economic structures."Ricardo Gómez-Carrera"The World Inequality Report 2026 is an outstanding achievement: the definitive resource to monitor the evolution of inequality globally, in all its dimensions. It is a true global public good and a vital input for the public conversation throughout the world. We should all be immensely thankful to its authors who are doing such a service by disseminating this knowledge, for the benefit of all."Gabriel Zucman
