I've heard some pretty horrid stories about foster families...Some are in it just for the money...
I can't speak for other areas, but in the area but the two areas I lived in the screen process was rigorous. There was one family that did manage to slip through the cracks and were in it for the "Farm help".
The kids slept in the basement on mattresses.
That was how my wife and I got involved in Foster care. One of the kids was a student of mine and let slip about the living arrangement. My neighbor was an adoption case worker. Same agency different department.
He spoke to the supervisor and the "fit hit the shan"
Andy asked my wife and I to consider getting our certification and the rest was history.
This is true; but I want to hope for the best.
