I have looked into this in Britain and in other countries for a long time. There is a documentary out of Britain on this exact subject called 'Traffic' - it was banned by the UK government, but can still be found in the US I think. I highly recommend it, it demonstrates how the SS are often literally financially gaining from the process of literal kidnapping.. Some of the scenes in this documentary are as grotesque as the animal slaughter documentaries but this one just involved Government agents taking children.
