http://www.thisamericanlife.org/radio-archives/episode/454/mr-daisey-and-the-apple-factory This podcast episode is basically a guy who did interviews and tours of factories in China, including Foxconn. Apparently almost every consumer electronic gadget we have was assembled by cheap Chinese hands. At current wages, it's more expensive to make a machine do it than people. One person's job is to polish iPhone screens all day. They use hexane instead of water or alcohol to wash it because hexane evaporates slightly faster, meaning faster production. However, hexane is a neurotoxin to inhale, sucks for the girl who's job is to polish our iPhone screens. It's a really excellent listen. He basically just tells the story of his time in China, and at the end you get some rebuttal of some stuff from some experts and fact checks.
