And things are only likely to get worse for China. Because of the one-child policy, China will soon suffer the most severe aging process in human history. The ratio of Chinese workers per retiree will plummet from 8:1 today to 2:1 by 2040. The fiscal cost of this swing in dependency ratios alone may exceed 100 percent of China’s GDP. The American working-age population, by contrast, will expand by 17 percent over the next 40 years. America’s fiscal future may not be bright, but it is brighter than China’s.
