For Sullivan there were two options for society: Feudalism and Democracy. Feudalism was simply an adherence to the primary natural law: might makes right. For Sullivan, Feudalism described much more than just medieval peasants -- it described Sullivan's America, where a laissez-faire economy fed into a legal, theological and philosophic system that promoted a "great system of business enterprise." He even described those commissioning skyscrapers as a "modern feudal baron" creating a castle for financial gain.

It is interesting then to remember that Sullivan is considered by many to be the father of modern skyscrapers. The reason for this is, at least early in his life, Sullivan did not fight the rise of skyscrapers because he believed that social issues like increasing rents and denser urban settings dictated the existence of skyscrapers. Instead, he sought to discover the essence of skyscrapers so that he could discover the solution to them. He said "it is of the essence of every problem that it contains and suggests its own solution. This I believe to be natural law." By looking at both this statement and Sullivan's claim that "form ever follows function", Sullivan is saying that the solution (the form) of a problem like skyscrapers arises from the problem itself (the function). So Sullivan sought to discover what skyscrapers should be based on the social issues they reflected.
