The Hunger Games is coded as a battle of adults versus children. Katniss’s parents are useless, from her dead father to her withdrawn mother who forces Katniss to care for herself and her sister. Katniss is the one to hold them together and keep them from starving, and through the book she dwells on her mistrust for her mother. Only Gale, a fellow teen and protector of his own family, can be relied on.
In Katmiss’ world, the older children protect the younger, as she does her little sister, or Rue does for her younger siblings. Since Rue is the eldest in her family, there’s no one to protect her but Katniss. Katniss realizes that Thresh and Rue would be her friends if not for the true enemy, the ones who hold the games.
Her true allies, she ones she shares sympathy with are the tongueless girl in the capital, Thresh, who would have been a friend, her hunting partner Gale back home. Even Madge, the baker’s daughter, gives her the mockingjay pin she wears as a symbol of home, while Katmiss discards her mother’s dress and shoes. Half the children in the games are relucntant to fight, from Thresh, who lets Katniss escape, to Rue, showing her she’s in danger from hornets, to Foxface, darting in to steal and run.
Adults are using her, from Cinna, who selects her dazzling outfits to show off his own talent long before he sees her as a person to Haymitch, who pushes her to shine for the sponsors. The Games themselves are the most fundamental example of this, run by adults to kill children for entertainment. In this world, the president is the ultimate adult and ultimate user, murdering families to control the victors of the games.
