The name of the game for DSS/CPS is to "nab" highly adoptable kids.
That's how they make their money. Crack babies are too hard to place.
That said, you are still quite right about the adoption bounty and the warehousing of children; it's the next best thing to placing the babies of unwed mothers who are in very short supply (and therefore bring in the big bucks. ) It's all a business. It's all one continuum which exploits people reproductively for the sake of the buck. Its time we woke up to that fact.
May God have mercy on us all
