It is not unheard of for parents in poor countries to sell their children. It is also not unheard of in poor countries for child prostitutes to exist.
I am aware.
But just sending kids back where they came from (if that can even be determined) is not much of a plan.
We will have to have cooperation of the home country regardless.
My guess is that we will end up paying these countries to take them. These countries will then end up selling as farm labor.
But, I have to hope that they are going to a more friendly hell than the one from which they were rescued.
