Not just BLOOD, Enviromental Issues Too!
All of those smelters don't meet any emission regulations that first world companies would have to meet. That's why Apple sources from them, for the reduced cost of manufacturing, not for it's social conscience. I hope SEC makes them bleed.
The same applies to most smelting or casting operations these days, that's why all those jobs went offshore.
Reduced or eliminated regulations = Reduced Costs
