The decision by South African President @CyrilRamaphosa to place inequality at the heart of the G20 agenda is historic. It marks a significant step forward on the long road toward greater equality. It is no coincidence that countries from the Global South—Brazil and South Africa—have led the charge to put tax justice and social justice on the G20 agenda in recent years. The World Inequality Lab wecomes @JosephEStiglitz's report and back its call for a global panel on inequality, modelled after the IPCC. It’s time to scale up the work we’ve championed for over 10 years to measure and address the drivers of inequality. ▶️
