What are you talking about? Do you think that Apple's iphones are produced by Apple's 50k employees? Apple isn't really a manufacturing company anymore, it is an engineering/design/marketing/retail company. But to manufacture Apple iphones, Apple Asian suppliers employ hundreds of thousands of people.

What you describe is much more an effect on the developed work of the migration of manufacturing jobs to emergent economies than that of technology, which, on the contrary, helps the developed world itself to slow down the loss of manufacturing jobs through higher worked hour productivity.
