Most foster children programs are handled locally. One problem is that there are not nearly enough resources to handle the number of foster children there are today. And to keep an eye on foster parents and foster kids, we'd need a lot more social workers, and in most places they aren't paid diddley, so there is a glaring shortage of capable workers.
I agree the system needs a total redo, but I don't see where the resources are. You know...money, personnel, will, political muscle.
