Krugman cites Apple as the largest company in the U.S. in terms of its valuation but having only 43,000 employees in the U.S. He asks the question- why does Apple get most of its manufacturing done in China? Apple indirectly employs about 700,000 people at its suppliers, with most of them in China. Companies contribute to a country's economy by creating successful clusters of research, innovation and manufacturing. In Apple's case, to the great detriment of the U.S. economy, the manufacturing part is being done entirely overseas. If cost is the only factor for this, then the question remains how German manufacturing has managed to surivive and grow with wages that are higher than in the U.S.
