An estimated quarter of a million children -- the world's tragic child soldiers -- are fighting in wars all over the world, living a life no child should ever have to lead. But across the planet, another crop of children, living in affluence in Cupertino, California, or Knightsbridge in London, or Berlin, are being recruited as child soldiers. They won’t bear arms. They won’t nudge from their posts – usually in their parents’ back bedrooms. On Halloween, while their peers are wearing goblin costumes and going from door to door, their families might regard them as hiding in their bedrooms and staying away from trouble.
