Is it selfish to choose not to have kids?

The village everyone keeps invoking has to be staffed by someone. 'It takes a village to raise a child' is quoted endlessly, usually by people contributing no villagers. Teachers, coaches, pediatricians, the teenager who babysits so parents can have a date night: this entire ecosystem of care depends on a steady supply of young people, both as recipients and eventually as providers. A society of only adults is a society eating its seed corn, enjoying the village while voting against its future. Somebody has to supply the villagers, and right now that somebody is always someone else.
