Fight Club, though, was just fancying up and decontextualizing the first sentence of Milton (EDIT: John Maynard, nor Milton) Keynes famous quote: "In the long run we are all dead. Economists set themselves too easy, too useless a task if, in tempestuous seasons, they can only tell us that when the storm is long past the ocean is flat again."
I would be very surprised if a financial news outlet choosing the Fight Club quote did so at random and not specifically because of its predecessor.
