So what? Isn't that how the world just works? Well, yeah—because we live in a capitalist system. (Most of us do, anyway.) But Marx's point is that the landowners and factory owners don't produce anything. They might hold the deeds or buy machines out of their company's earnings, but they're not actually doing any hard work. For guys like Marx and Mao, this was a big problem—but if the workers could overthrow the capitalists and claim the means of production for themselves, then all the workers of the world could live in peace with one another.
Against Zeena’s wishes, Ethan decides to bring Mattie to the station himself. In a fit of nostalgia, he takes her by a roundabout route, and they eventually end up stopping at the crest of a village hill in order to take a sledding adventure they had once proposed but had never undertaken. A successful first run prompts Mattie to suggest a second, but with a different purpose in mind. She asks Ethan to run the sled into the elm tree at the foot of the hill, allowing them to spend their last moments together. Ethan initially rejects her proposal but is slowly won over, and they take their positions on the sled, locking themselves in a final embrace. In the wake of the collision, Ethan comes to consciousness dazedly, reaching out to feel the face of the softly moaning Mattie, who opens her eyes and weakly utters his name.
