The explosion

Despite the world’s population exploding, Santa had to do with the same number of elves and reindeer.
They had to start work earlier and earlier in the year, and work longer hours.
And the earlier they started, the more changes to wish lists there were.
The kids themselves moved around the lists from nice to naughty and back again.
Not to mention the fakes and scammers and scalpers.
Santa tried to computerize it all, but it’s hard powering workstations and a datacenter that far North.
He broke down, ended up in a Norwegian asylum, and sits staring at the trees.
