Your facts don't support your assertions.
Population of China (2007): 1,321,851,888 (http://www.infoplease.com/ipa/A0004391.html)
Suicide rate determined in 2007: "more than 287,000 people end their own lives every year" (http://www.chinadaily.com.cn/china/2007-09/11/content_609571...)
Suicide rate per 100,000 per year: 21.7
Statistically expected suicides at Foxconn per year: 206
Actual suicides in 2010: 14 (http://topics.scmp.com/news/china-news-watch/article/Struggl...) with at least 30 attempts (http://blogs.telegraph.co.uk/news/malcolmmoore/100039883/wha...) (the articles contradict themselves in the number of attempts)
You are assuming the suicide cluster is a continuing trend rather than a short-term incident. Statistics does not work that way, things are not neat and orderly and you can't extrapolate like that. Besides, suicide clusters are a known phenomenon (http://news.bbc.co.uk/1/hi/uk/7205141.stm).
Also bear in mind that other sources place China's suicide rate much lower by a factor of as much as 4 (but Foxconn's suicide rate would still be lower than the average).
Is it something to be concerned about? Of course. But it's not at the dark-forces-at-work stage. All you are witnessing is how sausages (or cheap Chinese-manufactured goods) are made; witnessing it is uncomfortable but how often does it turn someone vegetarian?
