据世界著名咨询公司麦肯锡研究:进入21世纪初,美国所有工作中,80％以上属于知识服务型工作。有资料表明:20年代,一辆汽车的成本,85％支付给流水线上的工人和投资者。而到了90年代,这一比例已降到60％以下,其余都给了从事产品设计、战略咨询、融资计划、法律与会计服务、广告营销等人员。这就是服务业的魅力。 According to McKinsey, a world famous consulting firm, at the beginning of the 21st century, more than 80% of all work in the United States belongs to knowledge-based service. Data shows that in the 1920s, 85% of the cost of a car was paid to workers and investors in the assembly line. By the 1990s, however, the percentage had fallen below 60%, with the rest given to individuals engaged in product design, strategic consulting, financing programs, legal and accounting services, advertising and marketing. This is the charm of the service industry.
