I want to be very clear what I mean when I say the word slavery. If you look it up in Webster's dictionary, the first definition is "drudgery or toil." It's become a metaphor for undue hardship, because we assume that once you legally abolish something, it no longer exists. But as a matter of reality for up to 27 million people in the world, slaves are those forced to work, held through fraud, under threat of violence, for no pay beyond subsistence. It's a very spare definition.
