In this entertaining short novel, Doctorow takes on the classic SF question of 'What if?' for something that genuinely could come to pass - the no wage economy, where everyone gets the basics they need and it's up to them, through ad-hoc arrangements, to find ways to earn social credit to get more, should they want it. In a way, the social credit (known for unexplained reasons, unless I missed it, as Whuffie) is the equivalent of the rating system in the Black Mirror episode where everyone constantly rates everyone else. The other major change to society, which is far less likely to happen, is that when someone dies they are recreated from a clone which is imprinted with their backed up memory - so death becomes a minor irritation (unless you aren't entirely comfortable with a copy of yourself being a true replacement), while some choose to be put to sleep for thousands of years.
Our hero, Julius, ends up at Disney World, where he works with a group that help maintain and run a group of the attractions, in a period when some of the traditional attractions (the gem of his group's collection is the Haunted Mansion) are being replaced by direct brain access experiences. The main thread of the story follows Julius's attempts at guerrilla action to save his beloved ride in a world where social capital is everything.
On the whole the novel works well - Doctorow manages to be genuinely interesting about the challenges faced by a society where no work is required and lives are indefinite, while never getting into boring polemic. The storyline had some small issues for me, particularly when an outcome is flagged up very early - but I really enjoyed this book, which feels like the kind of thing Pohl and Kornbluth would be writing now if still around - no greater accolade - and I will certainly be trying more of Doctorow's output.
