John Oliver did a great show on chocolate around Halloween time. It showed just how much child labor goes into producing chocolate for the world, when almost no one really spends any time thinking about where it comes from.
The CNN clip in that video, is even better: the reporter gives the guys a bar of chocolate, and they go all "ohh, it tastes so great!". Then he asks them if they'll give any to the children, to which the guy answer "they can have the wrappers"... at which point the reporter produces out a second bar saying "don't worry, give them this"... still, I don't recall the kids getting any.
I enjoyed the part with the other journalist where he was on the phone with someone who hung up when the reporter pointed out that kids could stop working if their parents made more money. Insane that he was defending that practice.
