While both Slim and Curley wield a certain influence over the men of the ranch, their contrasting approaches illuminate a crucial distinction between power earned through respect and control enforced through dominance.
Slim, with his quiet confidence and effortless competence, inspires admiration and trust: "His authority was so natural that he never had to exert it."
He speaks sparingly, yet his words carry weight, as when he "calmly and inexplicably" resolves the situation with Lennie in the barn. In contrast, Curley, fueled by insecurity and a thirst for validation, resorts to bullying and manipulation: "He was young and quick, and already he disliked this giant ... He swaggered into the room." His attempts to assert authority are clumsy and transparent, eliciting fear rather than respect.
