Passage 2
If you still think Asia is cheap or even a bargain, compare office rents in Shanghai or Jakarta with those in Chicago and Paris. Or try to hold a qualified manager in China against the almost weekly job offers he receives due to the shortage of Chinese professionals. Since a happy employee is a productive employee, think about keeping someone in Singapore, where a 1,200 sq. ft. flat sets you back $2,000 a month, when for the same price you could be providing a comfortable 3,000 sq.ft.4 - bedroom house only ten miles outside Washington D.C.

No wonder companies are voting with their feet in response to Asia's rising costs. Matsushita, Sony and Honda continue to move production out of Japan. Taiwan's Nan Ya plastic is establishing factories in North Carolina and Texas that will export finished products back to Asia. Germany's Siemens is dumping Singapore in favor of lower cost locations in the region. The way things are going, Siemens may have to move again before long.

39. What does make the author think that Asia is not a cheap place any more?
40. Why does the Taiwanese company establish factories in United States and export products back to Asia?
