Much as I love Neal Stephenson's novels, I really wish he'd stayed around at the writer's class he surely took until they had learned how to wrap up books and write endings; more often than not, I turn the page on a Stephenson novel only to find it was the last...
(While I exaggerate a little, his stories do not end as much as END - I would be thrilled if he could spend a few pages wrapping it up in the end before leaving us waiting for the next title...)
The yarns he constructs are definitely entertaining enough for me to cope with this very minor annoyance, though.
Came here to say this. Both Seveneves and Fall have long unending psuedo-epilogues which add little to the main story, but also don't really wrap anything up satisfactorily either.
The public are being told that the UK can't afford to pay healthcare staff market rates, and so they are all leaving the NHS. The result is this dip in GDP, which IMO is more expensive.
