People will suicide if their families get money for doing that that. Stupid? Sure. There is no slavery on Foxconn plants, anyone can go away and grow some rice peacefully.
While it's not slavery in the traditional way, it sure is when you pay workers virtually nothing for a product that's overpriced.
Think a situtation where you'd be an administrator for Amazon and you're getting $10/day just because you live in <x> country, while your other _only_ option is to - as you said - "go away and grow some rice".
While this is a completely legal action, would you say that it's also ethical?
But no, whenever a f*cked up situation is not near our own precious asses, it doesn't matter. They can go out and grow some rice.
