The main problem is that not everyone understands how the "child protection system" should work. I'm silent about something, that unfortunately in Russia "children's homes" are often worse place than the home of parents of drug addicts and drunks. After all, there they are not simply not taken care of, but also mocked in a triple stronger than at home. Sometimes drinking parents, there are different people, rarely, but it happens. But vigilant neighbors (often old people) do as they please, and the "child protection system" does not listen to those who need it.
Fully agree with you @zhivchak In Russia there are not so many foster families and children are being put directly to orphanage in such cases
