Paradoxically, one indicator that has been improving steadily in the US – productivity – may be the clearest sign of the problem. When it comes to productivity, managers either invest in employee training, more efficient manufacturing processes, and the like, or they take steps that appear to boost productivity in the short run but that erode it in the long run.
荒谬的是，在美国有一个指标一直在稳健增长——生产率——可能是这一问题最明显的迹象。当说到生产率的时候，经理们要么在员工培训、更高效的制造工艺等等上进行投资，要么采取似乎能在短期内推进生产率但是在长期内损害生产率的措施。
