That's all there is to it. There's no heaven they reach where they're rewarded for getting a certain amount of the money. That's not how they think.
It's always "more"; never "enough".
@OutOnTheMoors And I think it's important to note that "more money" is the basis for decisions — not ethics, not morality, community, not even law: if violating any of those will produce a net profit (e.g., after fines and settlements and legal costs), most corporations will decide to go for the money.
@OutOnTheMoors The Ford Pinto and its exploding gas tank (that sounds somewhat like a Tom Swift novel) is the canonical example:
"It is not the person who has little, but the person who craves more, that is poor."
