Maybe I'm the one missing the point about greed. Maybe the fact that there's no end to it is the whole point, and it's because no amount is ever enough that a greedy person can continue to pursue wealth forever. In other words, it's not the result of attaining wealth, but the process of attaining wealth that holds appear.
If you gave your cousin a billion dollars, he wouldn't even care, because he'd still want more just as much as he did before.
