I don't think it takes an impoverished background. Just caregivers that hammer home the notion that "no one cares what you want!"
(Unfortuately, when my 6 year old son was whining a never ending litany of "I want... I want... I want", I snapped and explicitly said in a fairly loud voice "No one cares what you want!" I wish I could take that back. Maybe I can with better messages given over time. But most of the time, children don't and shouldn't get what they want, so it's kind of tricky)
a fine and enviable madness, this delusion that all questions have answers, and nothing is beyond the reach of a strong left arm.
