Article from Oct 2 2010, doubt they have increased their wages much more since.
Who in the US do you know that would find that wage acceptable? If they got paid regular US min wage that would be about 4x more than they pay someone overseas.
Do you think the company or the consumer would take that hit?
Even with a US worker the other costs involving making the phone are still substantially larger than the costs of labor for it. I doubt the labor costs involved equal anymore than a dollar or two with a US worker and certainly are below that in China. This isn't a car or something that takes hours to assemble. Its a matter of minutes. A group of ten workers probably gets hundreds of phones out an hour. So even if those ten workers made 10 an hour, it would cost less than 100 dollars to make those hundred phones coming out to 1 dollar per phone. I haven't seen any prices go down from outsourcing because the companies never pass the savings to the consumer. They keep those savings.
