Effect on the end price?
Since most of the products we buy are assembled in China by near slave labour, I'm not sure many people are able to criticise Dell et al, given that we're buying the shiny stuff cheap no questions asked.
But is there any good evidence to explain what is the impact on the end product price of (a) some living wage and decent working conditions in China, and (b) making the product in the US or Europe? If we wanted to get all ethical, how much would the price tag be?
The second part of the obvious question is who currently benefits? Does it translate to some definition of excess corporate profits or is it consumer price savings? For Apple it seems to certainly be excess profits, not sure that's always true away from the "price setter" firms.
