A long-overdue shift for the U.S. economy from borrowing, importing and spending to paying down debt, saving and exporting has begun, according to The Economist. Policy decisions within and outside the country will determine how far the change goes, The Economist notes. "American consumption and borrowing can no longer be the engine of either America's economy or the world's. That is the hope," The Economist concludes. "The fear is that politicians everywhere are incapable of dealing with the consequences."
