Stephen King The Soothsayer?

I do love a good Stephen King novel even if he does tend to bloat his books these days and you can read 30 pages which go nowhere and you think well i could have skipped that bit but back in 1982  he was in his pomp and he put out a novel set in a dystopian United States called The Running Man and based it in 2025.  
In 2025 the American nation's economy has tanked, Climate Change is running away and the country is run by power-crazed despots who pump out misinformation and propaganda and run a Game Show where contestants are on the run from a crew of assassins and if you survive you win a massive cash prize, get caught and your grisly death is live-streamed.
To be fair he isn't far wrong in the 2025 he envisioned.
