IMHO, the Hunger Games portrays a completely plausible future – as today – and still as per William Gibson’s famous quote – the future is already here, just unevenly distributed.
In the Hunger Games, the future has come and gone, with the technologies which support state oppression far advanced, and evenly distributed while others which could help those who would rebel against the state, non-existent, likely banned out of existence or only allowed for the tiniest elite.
As far as I’m concerned this is reasonable – technologies the internet do not exist in the Hunger Games because the state has banned their use – we see the seeds of this banning even today in acts like SOPA, PIPA and ACTA. There is nothing more dangerous to a state that free speech.
The only technologies which are portrayed in the film are the technologies of oppression, everything else – all technologies which could be used to overthrow the totalitarian regime of the Capitol, including any kind of ability for the people of the Districts to communicate with each other, have been outlawed.
Tomorrows world of “The Hunger Games” doesnt just showcase the reality TV spectacle of teenagers battling to the death — it also features futuristic hovercraft, force fields and bioengineered “Mutt” creatures. Those technological marvels represent tools of oppression for the dystopian nation of Panem, where the Capitol elite live in high-tech luxury supported by the old-fashioned sweat of district coal miners, farm hands and factory workers.
