People will always think about keeping their own sweet comfort before anything else in the world. And then, they will try to get some more if they can. Meanwhile, for some weird reason, they won't really bother themselves with all the poverty in the world, because there is simply nothing relevant enough they can do about it. It's called individualism.

It's not a matter of rich people hoarding wealth, it's just that it's culturally natural to behave that way. Nobody blames rich people, it's just that everybody is jealous. There is nobody else to blame than every each of us, collectively.
