What does the prince of the ranch means in Of Mice and Men?

Steinbeck uses the metaphor 'prince of the ranch' to show how Slim is highly respected by all the ranch workers and is a natural leader. His great skill and depth of perception mean he is revered and emanates depth and understanding. The other characters look up to him as worldly and wise, as shown later in the passage:

'His authority was so great that his Word was taken on any subject, be it politics or love.'

Arguments could be settled by Slim, as he is presented as intelligent and influential. The other characters have been stuck on ranches all their lives, but Slim gives the impression he knows a lot more about the world, and the ranch workers see him as a hero to emulate.
