I might give some pointers on greed, but you'd probably need to read up on it by a behavioral expert in ownership/accumulation incentives, both culturally and psychologically.
The short of the long story is - and this is only scratching the surface, which a behavioral expert will give good data & explanation for - that people being people think about themselves first, and everyone else second, naturally. Exactly where the human psychology begins and where the culture ends, is probably best explored by an expert, and I ain't one, I'm just a foot soldier, but I do know there's a bunch of overlap between culture and psychology, where the two join.
