Indeed, a CBO rule of thumb equates a sustained one-percentage-point shortfall in real GDP growth with budget deficits that are roughly $3 trillion larger over a ten-year period. Needless to say, such an outcome would spell serious trouble for America’s already-contentious deficit-and-debt debate.
事实上，联邦预算委员会的经验规则表明，真实GDP增长率持续短缺1个百分点相当于在10年的时间里增加大约3万亿美元的预算赤字。不消说，这样一个结果将大大激化已然莫衷一是的预算-债务争论。
