Again, why do you think a death by suicide inside the factory is unusual?

Suicide is a leading cause of death in every single country in the world (albeit it doesn't always appear to be so because of the way it's counted) and so when you have a very large employer you're going to see many deaths in their workforce.

Every death by suicide is a tragedy for that person and their loved ones, but I'm not seeing anything that says Foxconn have unusually large rates of deaths.
