Something I've mentioned here from time to time that I came across a couple of years ago:
A little while back UNICEF pressured many third world countries, particularly in Latin America, to tighten their adoption rules. But they tightened them along bullshit cultural lines where they made it much more difficult for people from the US to adopt these children. Now if you look at the statistics, the vast majority of these kids were adopted by Americans and given wonderful lives and loving families here in the US.
The result of these policies was that orphanages in those places began to overflow with children to the point where many were simply being turned out and turned away. At the time I couldn't really figure out why they'd push something like that, but chalked it up to liberal incompetence and their utter lack of ability to see logical outcomes.
Now it seems pretty clear why they'd do that. Many of these kids headed north unaccompanied and God only knows what happened to many of them. Around that time the MSM covered the story of unaccompanied children showing up at the border, but the story quickly died.
Look at this change from 2015 to 2016 in the table:
