One of the main topics of cultural conversation during the last decade was the supposed “fertility crisis,” and whether modern women could figure out a way to way to have it all—a successful, demanding career and the required 2.3 children—before their biological clock stopped ticking. Now, however, conversation has turned to whether it’s necessary to have it all (see Anne-Marie Slaughter) or, perhaps more controversial, whether children are really a requirement for a fulfilling life. The idea that some women and men prefer not to have children is often met with sharp criticism and incredulity by the public and mainstream media.
