In the 1955 movie version of East of Eden, the legendary James Dean plays
Cal.  Like Cain in Genesis, he competes with his brother for the love of his father, a moralizing patriarch.   Cal “goes long” in the market for beans, in anticipation of an increase in demand if the United States enters World War I.  Sure enough, the price of beans goes sky high, Cal makes a bundle, and offers it to his father to make up money lost in another venture.  But the father is morally offended by Cal’s speculation, not wanting to profit from others’ misfortunes, and angrily tells him that he will have to “give the money back.” Cal has been the agent of Adam Smith’s famous invisible hand:   By betting on his hunch about the future, he has contributed to upward pressure on the price of beans in the present, thereby increasing the supply so that more is available precisely when needed (by the British Army).  The movie even treats us to a scene where Cal watches the beans grow in a farmer’s field, something real-life speculators seldom get to do.
