That seems to imply that the grandparents are both capable and willing to help raise other children. Like it or not our culture in the US is very independent and an not insignificant number of parents think that their children are on their own once they hit 18. When you couple that with other parents who are in a financially shitty situation and already need their children's help, you are still going to get a lot of young people who feel that they do not have the resources to raise a child.
