You totally missed the point. How many other factories in the world has suicide nets?
It would also be nice if you referenced your numbers so we know where you are getting them from. As far as i know you are pulling them out of thin air.
I suppose you are running Safari. Open a new page, type in "suicide rate usa", click on the Wikipedia link. Then type in "population USA". Now take the two numbers that you found, 12.0 suicides per 100,000, and a population of 314 million. Open the calculator, enter 12 * 3140, and you get the number of suicides per year.
The reason why there are suicide nets is that at Foxconn: Most of the workers also live at Foxconn, closely together with other people, so someone who is suicidal can't go home and swallow 50 sleeping tablets and not be found until they are dead. And they can't take their gun and shoot themselves (which is what suicidal male Americans tend to do, which is why the "successful" suicide rate among US males is almost four times higher than among females, while the number of attempted suicides isn't), because they don't have guns.
So anyone working at Foxconn who is suicidal will attempt suicide where they work, because that is where they live, and since there are always people nearby, they have to find a way that works very quick and can't be stopped. Cutting your wrists doesn't work if you are found a minute later. So someone found a method that worked, and that got copied, and Foxconn did something to stop it.
My company doesn't have suicide nets. Why? First, because the place where I work could statistically expect an employee suicide every fifty year. Second, because if anyone wanted to commit suicide, they'd do it at home or someplace else, not among their workmates. Third, because the building isn't high enough; you'd most likely survive jumping from the roof with some severely broken limbs. Fourth, you can't get on the roof anyway without a key.
Now, a quote from Wikipedia about the Golden Gate Bridge between San Francisco and Marin County: "On October 10, 2008, the Golden Gate Bridge Board of Directors voted 14 to 1 to install a plastic-covered stainless-steel net below the bridge as a suicide deterrent. The net will extend 20 feet (6 m) on either side of the bridge and is expected to cost $40–50 million to complete. However,
lack of funding could delay the net's deployment." There are more suicides every year at the Golden Gate Bridge then at all of Foxconn. But nothing is done about it, for purely financial reasons.
Another statistics from Wikipedia: "In the United States, jumping is among the least common methods of committing suicide (less than 2% of all reported suicides in the United States for 2005). In Hong Kong, jumping is the most common method of committing suicide, accounting for 52.1% of all reported suicide cases in 2006 and similar rates for the years prior to that." Maybe that gives you a clue as well. Americans just don't jump from the roof of their company to commit suicide, they go home, take their gun and shoot themselves instead. Suicide nets wouldn't help (except at a focal point like the Golden Gate Bridge).
