The culture hasn't brought them up to be that way.

In this patriarchal society, biological parents, as a whole, do not just naturally have any particularly special inclination to be concerned about their children's health or different genetics. I do think most of them have the idea that they should feed and clothe the child but that's also mixed up with all the training they got about needing to use violence to discipline children. Anyways, things are changing. But I don't think a healthy society that cares about the well-being of children would have any ICE detention facilities and we have a bunch of them now.
