I agree that greed is timeless, but so is an underdog story:
Take your pick: Willa Cather, "There are only two or three human stories, and they go on repeating themselves as fiercely as if they had never happened before," or Shakespeare, "All the world's a stage, and all the men and women merely players; They have their exits and their entrances...Last scene of all, That ends this strange eventful history...sans everything."
