Then, explain whether research supports the assumption that foster care is harmful for children, as presented by the cornerstone argument for family preservation. Be sure to include whether you agree with this assumption and why you agree or disagree. Subsequently, identify the gaps in your state foster care system that contribute to the idea that foster care is harmful to children. Then, compare the benefits and shortfalls of permanency planning and family preservation. Finally, provide a description of whether you prefer the permanency or the family preservation approach as a child welfare social worker and why you prefer it.
