It would. I know that adoption seems very off-putting to many people, perhaps because it involves social workers and seems to open people's private lives to scrutiny. I would bet that more presentations from successful adoptive families in friendly venues (like churches) would help.
You bet ya!
One of the first steps would be to reform the foster care system so those kids can be adopted. The system in my state has the lovely habit of actually removing foster children from homes where they feel the kids are bonding. As for adopting you can forget about it, even if they kill one of their children parental rights will not be terminated and after they get out they are reunited with their non-murdered children. I get so frustrated some times I could spit.
Another thing that needs to be done is, "All adoptions are final 30 days after the papers go through." People are scared to adopt because the birth parent can come back up to two years later and take the child back.
This is one reason why overseas adoptions are popular.
