You've identified that slave labor happens in the US prison system and elsewhere, I think that most people would agree with this. I don't see any evidence that slave labor comprises "a large amount of what you use."
Well, no, most people don’t realize US is using slave labor. Most people believe China does, though, despite no proofs. Sadly, people are still quite disconnected from verifiable reality.
Perhaps because of the suicide nets? I get the Foxconn is not technically slave labour, but you must admit that suicide nets may give to the observer the impression that the gap is not that large between whatever it is and slave labour?
I lose workers to foxxcon all the time. They are one of the best companies in SZ to work for, with high wages and good benefits.. I dont think many people in CN would agree with your definition of what slave labor is
To note, I don't actually have an opinion on if foxconn is slavery or not, my point was that they can easily appear that way to outside disinterested observers purely based on "they have suicide nets around the buildings" because of the obvious implications thereof, and also the spattering of news stories that play up those implications.
