Capitalists control media and publishing and they're class-conscious
Popular "revolutionary" fiction will either have the revolutionaries be arbitrarily evil, misguided, obnoxious or, most sinister and subtle of all, simply fight to recreate a staus quo that the story's villain/s had destroyed prior to the hero's journey
Either way, a story about characters fighting to control the means of production and destroy capital will never be allowed to gain widespread circulation
