Who is the rich kid in Naruto?

Could you please elaborate on who you believe to be the "rich kid" in the anime series Naruto? Are you referring to a character who comes from a wealthy family or one who exhibits traits associated with affluence, such as a lavish lifestyle or a sense of entitlement? If so, could you name a few candidates and explain why you think they fit this description? Additionally, it would be interesting to discuss how their background and personality may have influenced their role within the Naruto universe.
