In the popular consciousness, “slavery” has come to be little more than just a metaphor for undue hardship. Investment bankers routinely refer to themselves as “high-paid wage slaves.” Human rights activists may call $1-an-hour sweatshop laborers slaves, regardless of the fact that they are paid and can often walk away from the job. But the reality of slavery is far different. Slavery exists today on an unprecedented scale. In Africa, tens of thousands are chattel slaves, seized in war or tucked away for generations. Across Europe, Asia, and the Americas, traffickers have forced as many as 2 million into prostitution or labor. In South Asia, which has the highest concentration of slaves on the planet, nearly 10 million languish in bondage, unable to leave their captors until they pay off “debts,” legal fictions that in many cases are generations old.
