Twenty-four years ago, I found myself hanging out virtually every day in the Henry Horner Homes, a Chicago housing project on the city's hardscrabble West Side. I had begun to immerse myself in the lives of two young brothers, Lafeyette and Pharoah Rivers, in an effort to understand what it means to be growing up poor in the world's wealthiest nation. Mother Teresa had visited this neighbourhood just a few years earlier, and what so struck her was not the poverty of the pocketbook - she had certainly seen worse in India - but rather what she called “the poverty of the spirit”. Indeed, it was a dispiriting place - especially the shootings which had become such a regular occurrence that the kids knew the drill: crouch in their windowless hallway of their apartment until the gunfire stopped - and count to make sure everyone was there.
