Freedom of the Seas. GPS. The Large Hadron Collider. These are all public goods that make our world more prosperous, accurate, and knowledgeable. But we don’t always give them the attention they deserve. Today on the show, the Planet Money book’s main author Alex Mayyasi joins us to take an audio world tour of spectacular public goods, one whimsical postcard at a time. These postcards are gorgeously illustrated in the Planet Money book. Come see Planet Money live on stage in April! 12 cities. Details and tix here: https://tix.to/pm-book-tour.
