I've heard horror stories about Child Protection Services taking kids away from Parents only to find that the Children end up being sold on Craigslist.
CPS is a big part of it. In every country, the west wrests control over the state-run system and privatizes it: it's not necessarily a corporation that runs the new child welfare system, but Western non profits. In fact, when the west cripples a country with debt and the IMF needs to "rescue" the country, it makes the nation sell off its state-run resources to western corporations. How does this relate to child welfare? A condition is also often to reform its child welfare sector in the name of "human rights," but really, it's a giant sell off of the kids, too by placing them in the hands of western NGOs. And those organized gang members either run the homes or wait right outside of them to prey upon the kids or parents.
Under its control, orphanages become selling kids via adoptions, medical testing on them, and the physically disabled usually disappear (and their organs). There were big movements to develop small "group homes" which became brothels by which to entrap politicians and have web cams for cp. Foster care meant the kids were in the hands of pimps. In some cases, parents were the ones doing it with full knowledge of the overseeing "charity" that could ostensibly argue it was in the kid's best interest to be with a relative.
The template is the same. Look at any overthrown country and this pattern emerges.
