The first thing I would say is that human trafficking is a criminal trade, and it's estimated that profit is at $150 billion per year, so there's money changing hands with recruiters. One of the preconditions we spoke about earlier for slavery to thrive is definitely corruption. In fact, if you look at the corruption index and overlay it with the countries with the worst slavery, you do see a massive parallel between those things.
You often have criminal activity in the places where slavery is, so you do need security around the investments you have. I think that's a critical point.
