Pope Francis answers that we don't know. My answer is humanity allows children to suffer. America spends $1 trillion a year on war andd $50 billion or so on international aid.

Psychic numbing--they can't feel the pain of people who suffer. See: www.oprah.com/omagazine/Psychic-Numbing-Why-We-Dont-Care-About-Darfur
