My understanding from news reports - correct me if I'm wrong - is that Foxconn employees tend to live in dorms and spend most of their time on company grounds.
Even if they're all going home and committing suicide there, the only evidence I've seen put forward for the supposed wave of suicides is the workplace ones. The stats there don't back up the claims.
Uh, does the fact that these employees tend to live in company owned dorms (ever heard of Mill Villages, "Company Store") and spend most of their time on company grounds not within and of itself something to question? Or even the fact that this has something to do with a (possible) higher suicide rate? Can you imagine living within a few hundred feet of your 60 hour manufacturing job with 3 other people in a 10 by 10 room, no time to visit family or have fun, enjoy yourself?
I think it's both a problem companies like Apple can do a lot more to address and likely to be significantly better than the alternatives most of the employees have available.
People aren't joining Foxconn from jobs where they've got 40 hours a week and vacation time. They're often joining from rural areas with subsistence farming, poverty, shittier jobs, etc. International attention on Apple and Foxconn likely prevent at least some abuses that are rampant elsewhere in China.
All that said, there's no reason we in places like the US can't pay $20 more for an iPhone.
Edit: Looking at http://www.wellness.com/news/6427/us-workplace-suicides-jump... , it looks like in the US workplace suicides are less than 1% of overall suicides. Doubtless different in China, but hopefully makes the point that comparing the two statistics is likely to be problematic.
