虽然制造业占私人部门就业的比例从2008年1月的11.9%下跌到2012年9月的10.7 % ， 但这只是自1970年代早期出现的长期大幅下滑趋势的其中一小部分而已，须知当时制造业所占的份额可是超过30 % 。
While the manufacturing sector’s share of private employment fell from 11.9% in January 2008 to 10.7% in September 2012, this is only a small portion of the enormous secular decline since the early 1970’s, when manufacturing accounted for more than 30% of private-sector employment.
