All that said, although the wealthy may not actually be intentionally malicious towards the poor, they are still not absolved of moral responsibility for their actions by saying that simply "anyone would do the same" or that they're just "playing the game" and "didn't write the rules". The unfortunate fact is that in a world with finite resources we really can't satisfy unlimited desire to posses material goods, and at a certain point the more one possesses the less is available for those in need.
The dehumanizing nature of it does bother me, though. It's the foundation of any war. And yet, although many wealthy people don't actually feel this way, the distribution of wealth might be seen to be enacted by someone that did.
Going back to your original comment, what I was trying to say was that the rich/poor divide isn't nearly as arbitrary as racial/religious divides. The rich/poor divide is increasingly important to be conscious of, and it's perhaps even more important to be conscious of the stratification that keeps people poor, and all the ways that robs a large chuck of humanity of its potential, which is what the piece is really about.
