You walk away from Omelas, but every other city state also has a child in a basement. All the states just use slightly different demographic criteria to pick the child.

N. K. Jemisin wrote something in conversation with that. It certainly gave me a moment.

The Ones Who Stay and Fight - Lightspeed Magazine

It’s the Day of Good Birds in the city of Um-Helat! The Day is a local custom, silly and random as so many local customs can be, and yet beautiful by the same token. It has little to do with birds---a fact about which locals cheerfully laugh, because that, too, is how local customs work. It is a day of fluttering and flight regardless, where pennants of brightly dyed silk plume forth from every window, and delicate drones of copperwire and featherglass---made for this day, and flown on no other!---waft and buzz on the wind.
