Most children in the foster system are not available for adoption. In the USA most children in the foster system are there because they have been taken from parents deemed unfit by the state. However the government believes in the right of the parents to prove that they are indeed fit to raise their kids and so as long as those parents wish to have those kids yet can’t prove they are fit parents those kids will remain in foster care. 

The sad reality of the foster system is that most of the older children will remain there no matter what because adoptive parents overwhelmingly want newborn babies. After getting approved to adopt a child the waiting list for a newborn will force you to wait 2 years or longer before you can have your adoptee.

Makes sense, unfortunate. I wonder how many children who return to formerly unfit parents end up facing the same mistreatment as before.
