NBC News recently reported that the US government pays $775 for each unaccompanied or kidnapped child per night to the for-profit private prison companies running the concentration camps. Separated children pay better than keeping them in a facility with their parents. Concentration camps for children are very profitable operations since all you need is a warehouse & concentration camp guards marinated in racist hatred.
This is a quite useful investigative report on the financial forces behind the concentration camp system which every day gets closer to the ethos of Auschwitz. Racism & fascism have a hand-in-glove relationship.
