I find all of this hand-wringing over working conditions to be the biggest pile of bunk that I have ever heard of.
The only reason that China is manufacturing just about every consumer product out there is that sending work there allows you to exploit cheap labor, lax environmental regulation, and other regulation found in western countries.
So now some westerners who "care" are waxing on about the poor iPhone workers. Why aren't the Chinese people making shoes, underwear, leather coats or other unpleasant jobs worthy of our pity?
