Ballard is more than worth reading. Novels and shorts stories alike. He nailed consumerism so perfectly it's frightening.
To me, one of the most striking book I ever read was 'Brave New World' (edit: I read it when I was not even a teen yet (now well into my 50s). It touched me lot more than '1984', that was also very striking mind you. Then, it would be 'Fahrenheit 451' both Bradbury's original 1952 novel and Truffaut's 1966 brilliant adaptation. Contrary to what most people will tell you, the real focus in Fahrenheit is on the place and role of TV in that a-cultured society more than the book burning part, imho. Replace 'TV' with 'social media' to make it more contemporary.
Bradbury was a book lover, and an avid reader. He also knew quite well the sad times it announces when a society as a whole stops considering reading books an incredibly valuable activity, or even just something remotely interesting.
Edit: clarifications.
