Apple can most certainly improve the working conditions at Foxconn, keep the price of their iProducts the same and still be one of the most profitable companies around.
So why are they not doing this if it is so obvious? I am sure they would be happy to pay you to point them in the right direction if it is obvious and they are too inept to see it themselves.
I am pretty sure there are people who care in most of the big companies. The question is can they do anything about it without getting fired even at the highest levels. Would you or I take that risk? Would those who are interested in buying their products pay more for products produced with reasonable working conditions and wages?
Based on a recent poll in this forum it seems not.
