Dannn, sadly thats how a lot of people view it albeit subconciously

Weve got used to seeing starving africans, dead asians, dead arabs all over the screen all from far far away places we dont know or care about. So of course you get used to it and it becomes far from your mind.
Those places really are a different "world" with many of these people living a life worse than animals here and what wed call subhuman conditions and behaviours (think hacking off arms etc - most people would think they are animals acting that way).
But when things happen closer to home, we can empathise with it because its a more familiar lifestyle etc.
Plus ultimately we are all inherently selfish. Would you step over the emaciated dying corpse of a etheopian to ensure you get enough food for you and your family?? (assuming theres not enough to go round) course you would.
