Some of the situations described sound absolutely terrible. While we're on the subject, though, I want to point out that slavery is a spectrum, not a binary condition. I don't doubt his number, 27 million, for a certain cutoff point of who is considered a slave and who isn't. If you move the cutoff around, though, you can truthfully say there are billions of slaves, or maybe even zero.
