In this episode of "Interesting Times," Ross Douthat interviews sociologist Dr. Alice Evans about the global fertility collapse. They discuss the rapidly declining birth rates across the world, the economic and social implications of an aging population, and the potential causes behind this phenomenon. Dr. Evans argues that a major factor is the "coupling crisis," where increasing numbers of people are staying single, driven by the rise of personal online entertainment and technology outcompeting personal interactions. They explore various solutions, including regulating technology, cultural shifts to promote coupling and child-rearing, financial incentives, and the role of religion, while acknowledging the limited efficacy of each intervention and the likelihood of a continued decline. They speculate on the political and economic consequences of this trend, including potential shifts towards conservatism and the need for young people to understand and address these challenges.
