So the equation is simple: 5.5%-1.5%-3.5% = 0.5%. That 0.5% is all that is left for job growth, because that's all the job growth required to meet demand given the remarkably strong rate of growth of productivity.
这点很容易说明。美国的总名目支出年增长5.5%，年通货膨胀率为1.5%。全员劳动生产率的年增长率为3.5%。所以用一个简单的等式表示：5.5%-1.5%-3.5%=0.5%。而就业率的增长就只能达到0.5%，因为尽管劳动生产率增长强劲，要满足需求却只需要这样就业率增长。
