These children would at least have the **possibility** of finding a stable and permanent home. Right now, they can linger for years, bouncing from foster home to foster home, with no hope of having a permanent place to call home. It is easier to find an adoptive home for a child who is younger and has only been in the system for a year than it is to find a permanent home for a child who is older and has lived in foster care for 5+ years.
I grew up in an unstable home. I know how damaging it is for a child. I still suffer the aftereffects of this as an adult. When someone does not know safety in childhood, he suffers well into adulthood.
