One might have expected this transition, which reached its pivotal year in the United States in 2000, to cause unemployment (at least until the economy adjusted), accompanied by a rise in productivity. But, in the years leading up to the 2008 crisis, US data show that productivity trended downward; and, until the crisis, unemployment did not rise significantly.
与此同时，信息技术和数字网络让许多白领和蓝领工作实现了自动化。你也许已经预料到了这一转型——对美国来说，2000年是这一转型关键的一年——导致了失业（至少在经济进行了调整之前是如此），并伴随生产率的提高。但是，在2008年危机前几年，美国的数据显示生产率存在下降趋势；并且，直到危机之前，失业并未大幅上升。
