However, the prospect of relocating manufacturing operations abroad raises new potential issues that must be considered. Specifically, it may be ethically permissible to take advantage of certain prevailing circumstances in foreign countries that are responsible for lower labor (and other overhead) costs. On the other hand, there are also limits to that concept. It is not ethically permissible to relocate manufacturing operations to countries where economic and social conditions are so bad that the population is desperate for work at wages that are exploitative by any objective standard.

Similarly, it is ethically unacceptable to allow American companies to exploit foreign workers by allowing manufacturing processes to be carried out in work environments that would violate the most basic concepts about appropriate and acceptable vocational situations and circumstances...

And subject to U.S. employment laws and standards set out by occupational hazard regulations.
Assuming that the company can ensure that the working conditions and employment wages in foreign countries under consideration are not exploitative or otherwise violative of basic ethical business principles that govern employment in the U.S., I am inclined to support relocating manufacturing operations abroad. In my opinion, high-tech manufacturing (as opposed to high-tech product and software development) need not necessarily be conducted in Silicon Valley, especially in light of the many factors that contribute to very high overhead costs in Silicon Valley. Manufacturing processes should be capable of being taught and exported to workers abroad at a fraction of the costs of centralizing manufacturing operations in Silicon Valley.
