But then again, it is Kurt Vonnegut.
In this story, we see an America where "Everything was perfectly swell. There were no prisons, no slums, no insane asylums, no cripples, no poverty, no wars. All diseases were conquered. So was old age."
The population of America had been stabilized at 40 million - which happens to be what the population was in 1870, or slightly more than one tenth of todays population.
So population is stabilized, and old age is conquered... What happened when babies are born? Well, somebody has to go. The easiest way to accomplish this is to call the Federal Bureau of Termination (phone number: 2 B R (naught) 2 B) and get an appointment at the municipal gas chambers. Unfortunately for the "Hero" of our story, his wife is unexpectedly delivering triplets, rather than a single child, and he only has one volunteer slated for the gas chamber. Which means two of his babies have to go.
You'll have to read the story to find out what happens next. With only 119 locations, it is undoubtedly a short story, perfect for a quick after dinner entertainment. Just be sure to leave yourself a little time at the end to contemplate the story, and re-read or peruse various bits of it. You won't be disappointed.
