During the recent G20 finance ministers meeting in Rio de Janeiro, Brazil's proposal for a global 2% tax on billionaires faced significant skepticism and was ultimately not endorsed, with only a vague mention in a draft communique. While the idea received initial support from some nations, including France and Colombia, top finance officials from the U.S. and Germany expressed concerns over its feasibility, preferring that each country develop its own progressive tax system. U.S. Treasury Secretary Janet Yellen acknowledged the importance of progressive taxation but emphasized the challenges of coordinating a global tax policy. Discussions are expected to focus on combating tax avoidance rather than implementing a new tax on the wealthy. The G20 leaders plan to issue a joint statement supporting progressive taxation without committing to the billionaire tax proposal, reflecting broader concerns about wealth inequality and the need for effective tax policies. In parallel, governments are negotiating a new UN tax convention aimed at promoting economic justice and wellbeing.
