It's hard to decide who's the most evil the prospective users or the crime syndicate.

It is a fact of human history that there has always been slavery and in all likelihood, there will always be those who are willing to make a profit off of the enslavement of others, and those who are willing to pay to have servants. Money is the driving factor, both in getting the women (or sometimes men) to put themselves out there for the slave traders and the operators of the systems that make it possible. Just like drugs, as long as there is a demand, there will be someone willing to supply it.

There are always individuals willing to prey on the vulnerable, albeit their own or another group. One of the ugly sides of the human species. We need to get trump out of office so that we can begin to Crack down on Saudi Arabia, UAE, and others complicit in the area for human rights abuses.
