It's easier to do horrible things to people if you don't really see them as people.
People are good people. If they know what's going on, and they can relate to it, they can be moved to do something. If they can never see it or never relate to it, they continue to stay disconnected.
The more that you dehumanize somebody, the easier it is to kill them... deport them... do whatever you can.
I think that my experience as a single mom getting into relationships in an impoverished district with men that don't have options resonates with people. I don't get into the deadbeat dad thing. I don't think men innately decide to be irresponsible fathers. I think there's a backstory. They're given really bad choices. It's less deadbeat dads and more unemployed fathers, and some fathers decide to sedate and give up.
