2017年三季度，美国的净国民储蓄率 — — 企业、家庭和政府部门储蓄之和 — — 只有国民收入的2.1 % ， 仅仅相当于二十世纪结束前三十年平均水平6.3%的三分之一。
America’s net national saving rate – the sum of saving by businesses, households, and the government sector – stood at just 2.1% of national income in the third quarter of 2017. That is only one-third the 6.3% average that prevailed in the final three decades of the twentieth century.
