We've done several podcasts on America's declining fertility rate, and why South Korea has the lowest birthrate in the world. But we've never done an episode on the subject quite like this one.Today we go deep on the psychology of having children and not having children, and the cultural revolution behind the decline in birthrates in America and the rest of the world. The way we think about dating, marriage, kids, and family is changing radically in a very short period of time. And we are just beginning to reckon with the causes and consequences of that shift. In the new book, 'What Are Children For,' Anastasia Berg and Rachel Wiseman say a new "parenthood ambivalence" is sweeping the world. In today's show, they persuade Derek that this issue is about more than the economic trends he tends to focus on when he discusses this issue.If you have questions, observations, or ideas for future episodes, email us at PlainEnglish@Spotify.com.Host: Derek ThompsonGuests: Anastasia Berg & Rachel WisemanProducer: Devon BaroldiLearn more about your ad choices.
