The skyscrapers reaching high into the urban madness of the city that gives Metropolis its title are representations of the economic inequality which drives the entire narrative of the film. The rich live in luxury high rises above the city, while the workers labor underground. The story moves inexorably toward a labor strike in which those down below rise up against the upper classes, but to disastrous effect. The film explores the exploitation of the working class by the ownership class. Throughout the film we see that society is split into those who work and those who do not, and a major tension in the narrative is the fact that the luxury experienced by the rich is at the expense of those working below.
