Well, I'm not sure that distance equates to an ability to do any good.
And besides, just because it makes you feel helpless and perhaps slightly guilty (and I'm not speaking of you personally) it's no reason not to be keenly aware of the disparity. I think more awareness and less centeredness on self ('because I can't do anything about it anyway') would go a long way towards turning public sentiment away from self-centered materialism and towards a more globally-centered awareness and stewardship.
Or at least that's what I'm trying to believe so as not to hate my own species.
