The pro-sweatshop argument is encapsulized in this example:
In an article about a Nike sweatshop in Vietnam, Johan Norberg wrote, "But when I talk to a young Vietnamese woman, Tsi-Chi, at the factory, it is not the wages she is most happy about. Sure, she makes five times more than she did, she earns more than her husband, and she can now afford to build an extension to her house. But the most important thing, she says, is that she doesn't have to work outdoors on a farm any more... Farming means 10 to 14 hours a day in the burning sun or the intensive rain... The most persistent demand Nike hears from the workers is for an expansion of the factories so that their relatives can be offered a job as well."
The contra argument seems dominated by appeals to emotion ala Mike Daisey:
"_____ can't even afford to buy the ipad he makes",
"_____ only makes X dollars an hour/day/week/month/year."
"X workers were injured/killed in this accident"
"workers often have to work overtime"
"workers have to stand"
I think Mike Daisey should spend some time in rural China with the relatives of Foxconn employees who do backbreaking farm work. But who would go to see that show without "Steve Jobs" in the title?
