The new Global Justice Report by the World Inequality Lab in France—which calls for caps on economic growth in rich countries, top income-tax rates of 90 percent, and a World Sovereign Fund to redistribute wealth to the Global South—has reignited one of the oldest debates in economics: How do we actually lift people out of poverty?
The data have never left much question. The answer is economic growth. Nonetheless, many development economists have spent decades arguing that growth isn't enough or as important as development aid. The French report is simply a radical expression of a popular view. So, it's worth reviewing the evidence again.
