In Sinclair Lewis's "It Can't Happen Here," the author highlights the complex dynamics of power and control, particularly in the context of an oppressive regime. Even when in possession of a large force, a leader must ensure that their followers feel a sense of freedom and purpose. If they perceive themselves merely as subjugated individuals, they may turn against their leaders and align with opposing forces. This underscores the psychological aspect of leadership and loyalty amidst coercion.

This commentary reflects the necessity of ideology in maintaining authority. Leaders cannot simply rely on brute force; they must inspire their followers with the belief in a common cause, familiarizing them with the value of freedom and their role in achieving it. This manipulation of perception is crucial in preventing dissent and maintaining stability within a controlling regime.
