To Crush Global Inequality and Secure Livable Future, Scholars Call for 90% Tax on Mega-Rich

A sprawling report released Thursday argues that averting the bleak techno-authoritarian futures now being sold to us and laying the groundwork for a just, livable future requires restructuring the world's economic order to widely redistribute wealth that has been hoarded at the very top for decades.The report, compiled by hundreds of researchers from around the world and published by the World Inequality Lab (WIL), is billed as the first comprehensive attempt to lay out a plan to reconcile planetary habitability and high well-being for all. Achieving that aim will be impossible, the authors argue, without a drastic reduction in inequality of income, wealth, and power.The current international order is plutocratic, said French economist Thomas Piketty, a renowned expert on inequality and co-director of WIL. It is essential to move away from this plutocratic system to a new democratic order.The report outlines a number of proposals that would redress staggering levels of wealth and income inequality. Currently, the top 10 of the global population brings in more income than the remaining 90 combined. Wealth inequality is even more extreme, with the top 10 controlling 75 of global wealth, compared to 2 controlled by the poorest half of humanity.Specifically, the authors call for a new, progressive global income tax that would peak at 90 for those who earn 5,000 times the average adult disposable income. They also propose taxing the wealth of millionaires and billionaires at a rate up to 20.Revenue from the new taxes would flow into a Global Justice Fund, which would distribute dividends to countries to help boost spending on climate, education, and healthcare. The fund would also invest in a World Sovereign Fund, whose returns on sustainable assets would be used to finance country dividends.The result is not a transfer from many to few but a gain for almost everyone, Piketty and other report contributors wrote in an op-ed for The Guardian. Close to 90 of the world’s population would double their income between 2026 and 2100, and once leisure and a habitable planet are counted, more than 99 come out ahead.Technical impossibility is not what is standing in the way, but rather the absence of a shared vision of social progress, at once concrete and radical.Redressing inequality would not be sufficient to secure a livable future, the report authors emphasize, given that continued fossil fuel use and expansion are pushing the world in the direction of climate catastrophe. What's required to prevent planetary disaster is a fundamental transformation of energy systems, the report argues.This means electrifying energy demand wherever feasible (such as transitioning vehicle fleets) and switching to low-carbon fuels (for example, in steel and cement production), the report states. Crucially, electricity generation itself must be decarbonized, moving away from fossil fuels toward renewables like hydropower, solar, and wind.The report also envisions a move away from overconsumption toward what the authors call a future of sufficiency, which would entail shorter work hours for the global labor force, changes to land use, and other reforms.Such ambitious goals will not become reality, the report stresses, without a powerful citizen movement and a dense network of broad-based organizations (including labor unions, political parties, civic platforms, and other collective initiatives) which are sufficiently well-organized and effective at promoting broad institutional and policy change.A habitable, equal, and prosperous 21st Century is materially possible, the authors declare. Technical impossibility is not what is standing in the way, but rather the absence of a shared vision of social progress, at once concrete and radical. What it will take instead is political choice, and the hard work of coalition-building behind it.
