In The Hunger Games, survival in arena depends on how many sponsors (who are rich) a contender is able to woo because it has been stressed so many times that supplies are expensive.
I can understand that advanced medicines which can quickly heal burns and reverse the effect of bites of a genetically-engineered combat wasp can be super expensive. But, why water and loaf of bread has to be expensive?
Has this to do with excessive taxation of the Capital or hovercraft (which drops supplies with parachute) service charge or game's monetization? I want proper citation.
