Inequality is always political choice and learning from policies implemented in other countries or at other points of time is critical to design fairer development pathways. Chapters 8, 9 and 10 of the report discuss various options to tackle inequality, learning from examples all over the world and throughout modern history. Recent developments in international taxation show that progress towards fairer economic policies is indeed possible at the global level as well as within countries.

A similar evolution will be necessary in order to address the challenges of the 21st century. This played a critical role in order to ensure the social and political acceptability of increased taxation and socialization of wealth. The rise of modern welfare states in the 20th century, which was associated with tremendous progress in health, education, and opportunities for all (see Chapter 10), was linked to the rise of steep progressive taxation rates. We stress at the outset that addressing the challenges of the 21st century is not feasible without significant redistribution of income and wealth inequalities. This vast network collaborates with statistical institutions, tax authorities, universities and international organizations, to harmonize, analyze and disseminate comparable international inequality data. The data and analysis presented here are based on the work of more than 100 researchers over four years, located on all continents, contributing to the World Inequality Database (WID.world), maintained by the World Inequality Lab. This report presents the most up-to-date synthesis of international research efforts to track global inequalities. Open-access, transparent, reliable inequality information is a global public good. Beyond income and wealth, it is also critical to improve our collective capability to measure and monitor other dimensions of socio- economic disparities, including gender and environmental inequalities. Accessing such data is critical for democracy. Economic growth numbers are published every year by governments across the globe, but they do not tell us about how growth is distributed across the population – about who gains and who loses from economic policies. We live in a data-abundant world and yet we lack basic information about inequality.
