For decades there has been debate at the highest levels of the Chinese

四月网 2012-02-06
《纽约时报》1月12日报道,原题:美国人如何输掉了iPhone的工作。以下是文章内容
摘编。
中国河南省2010年招聘会上,富士康科技有限公司的求职者蜂拥而至。
去年二月份,巴拉克•奥巴马在加利福尼亚参加矽谷名人们的晚宴,每个客人都
得到了一个向总统提问的机会。
但当斯蒂夫•乔布斯准备发问时,奥巴马总统打断了他,先提出了自己的一个问
题:怎样才能在美国生产iPhone?
不久之前,苹果还在吹嘘它的产品都是在美国生产的,今天事情已经完全不是这样了。
苹果公司去年卖出的7000万部iPhone、3000万部iPad和5900万部其他产品,几乎全是在
海外生产的。
奥巴马问,为什么不能把这些工作搬到家里来做?
乔布斯先生的回答含糊其辞,据参加宴会的人员回忆,他说:“这些工作回不来了。”
总统的发问触及了苹果公司的核心问题所在,这已经不仅仅是海外廉价劳动力的问题了
。苹果高层认为,海外工厂的规模、工人的灵活性、勤奋程度和操作技巧都已经超过了
美国工人。“美国制造”已经不是大部分苹果产品的明智选择... 阅读全帖 |

If you do not maintain your car (meaning regular oil changes, filter

The collapse of the Ming Dynasty was a protracted affair, its roots

Originally a vassal of the Ming emperors, Nurhaci in 1582 embarked on an
inter-tribal feud that escalated into a campaign to unify the Jianzhou
Jurchen tribes. Later Nurhaci announced Seven Grievances and openly
renounced the sovereignty of Ming overlordship in order to complete the
