We learn as children to scream, stomp, tantrum until we get our way if not corrected. My reward for being lugged around shopping all afternoon with my mom was ice cream at the end of the day. If I was overly difficult on a particular day, ice cream was denied. Tantrum ensued.
Years later, the perk of ice cream becomes the perk of power/authority. Try taking or lessening the power of an entitled one and expect tantrums. Many of them are still children, after all.
