Progressive Economists Propose Global Wealth Taxes and Green Policy Reforms
Global economic inequality, climate change, and artificial intelligence threaten financial stability, prompting a coalition of international progressive economists to propose sweeping policy overhauls. EL PAÍS reported that prominent researchers have outlined interconnected solutions, including global wealth taxes, restructured international financial institutions, and aggressive green industrial policies to address mounting public anxiety and the rise of right-wing political movements.
Gabriel Zucman and Thomas Piketty Target Global Wealth and Climate Justice
French economist Gabriel Zucman proposes a 2% tax on fortunes exceeding $100 million to fund public investments. Fellow French economist Thomas Piketty argues that wealth taxation must connect directly with climate action to avoid public backlash similar to France’s yellow vest protests. Piketty co-authored the Global Justice Project report, which outlines a framework to keep global warming below two degrees Celsius by 2100 while raising incomes for the global majority. It also proposes increasing global healthcare and education spending from 13% to 38% of global GDP, alongside a wealth tax of up to 20% on the ultra-wealthy. Branko Milanovic, an economist at the Graduate Center of the City University of New York, notes that the report provides a vital conceptual framework for tackling systemic global issues simultaneously rather than treating them in isolation.
Abhijit Banerjee and Mariana Mazzucato Call for Active Government Intervention
Abhijit Banerjee, co-founder of the Abdul Latif Jameel Poverty Action Lab and a Nobel laureate, contends that the European Union possesses enough market power to impose carbon tariffs on nations like the United States that lack adequate pricing mechanisms. Banerjee argues that framing climate policy around trade leverage could make carbon taxes politically viable across European nations.
Mariana Mazzucato, director of the Institute for Innovation and Public Purpose at University College London, asserts that public sectors must abandon neoliberal models of acting merely as market facilitators. Mazzucato points to historical precedents like the Apollo space program and modern industrial strategies in Brazil, where governments established clear directional missions to drive sustainable technological transitions.
