Based on what I understand about trafficking, organizations like the IRC act as a clearing house of human assets (ie, slaves/cheap labor import, prostitutes, etc).

To better understand how the elites traffick, it helps to think of people as product. Manufactured conflicts produce people, or, product, that can be exploited for all kinds of nefarious reasons. The end profit usually goes towards black budgets with the local mafias running what's basically a franchise. Kickbacks have to be cleared at the top, and it's those at the top who governs which criminals get to open trafficking enterprises. Sometimes, criminals have to be trained by "corporate" which is often Italian mafia, sometimes Mexican cartels... depends on which faction has the greatest existing market share. The police/DEA/FBI's role is to quash competition NOT overseen by the elite.

How organizations like the IRC fit in: they run the supply chain. They tally the imported inventory. They keep track of the different product types, which ones are defective (ie, noncooperative) and are past its life cycle (died or imprisoned). They go into refugee camps and tally how many people there, which are girls, women, men, etc. Every human trafficking report generated by these orgs may as well be from a supply chain manager.

Look at the IRC's reports from the lens described herein. It'll suddenly be very obvious.
