In society, we do horrible things to one another because we don't see the person it affects. We don't see their face. We don't see them as people. Which was the whole reason the hood was built in the first place, to keep the victims of apartheid out of sight and out of mind. Because if white people ever saw black people as human, they would see that slavery is unconscionable. We live in a world where we don't see the ramifications of what we do to others, because we don't live with them. It would be a whole lot harder for an investment banker to rip off people with subprime mortgages if he actually had to live with the people he was ripping off. If we could see one another's pain and empathize with one another, it would never be worth it to us to commit the crimes in the first place.
