The document discusses four major issues with the U.S. foster care system: 1) Overreliance on group homes where more than 40% of children in group homes do not need to be in that setting; 2) Lack of support for foster parents who need training and resources to care for children who often have mental/behavioral issues or trauma; 3) Many teenagers age out of the system without a support system and are at risk of homelessness or not graduating high school; 4) There is little focus on reuniting children with their birth families when possible, even though most children would prefer to live with family over being adopted or aging out.
