“Some have suggested that the U.S. is actually two countries in one — a developed nation for the rich and a developing one for the poor. But recent trends like the fall in construction productivity and the rise in health costs suggest that inequality isn’t the whole story here. The U.S. is simply becoming less efficient along a broad spectrum of measures. How long can this loss of efficiency go on without hurting the country’s overall wealth? Nobody knows, but if the U.S. does eventually backslide in terms of gross domestic product, it wouldn’t be the first rich country to have done so in recent years.”
