I'm so sick of this "greed is good" meme. A child's first experience with greed is usually eating too many sweets - they get sick and don't do it again.
The whole reason we're here on this earth is because we cooperate and depend on the "kindness of strangers". Greed invariably ends badly and
causes great misery to those on the receiving end of it.
