CAMBRIDGE – Perhaps for the first time in modern history, the future of the global economy lies in the hands of poor countries. The United States and Europe struggle on as wounded giants, casualties of their financial excesses and political paralysis. They seem condemned by their heavy debt burdens to years of stagnation or slow growth, widening inequality, and possible social strife.
Much of the rest of the world, meanwhile, is brimming with energy and hope. Policymakers in China, Brazil, India, and Turkey worry about too much growth, rather than too little. By some measures, China is already the world’s largest economy, and emerging-market and developing countries account for more than half of the world’s output. The consulting firm McKinsey has christened Africa, long synonymous with economic failure, the land of “lions on the move.”
