What does Huck tell Jim a king does in life

Huck talks about how rich Kings are and how they can do whatever they want,

“Get?” I says; “why, they get a thousand dollars a month if they want it; they can have just as much as they want; everything belongs to them.” “Make?” I said. “Why, they can make a thousand dollars a month if they want. They can have all the money they want since everything belongs to them.”

“AIN’ dat gay? En what dey got to do, Huck?”
