How the Supermarket Helped America Win the Cold War (Ep. 386 Rebroadcast)
47 min
Aisle upon aisle of fresh produce, cheap meat, and sugary cereal — a delicious embodiment of free-market capitalism, right? Not quite. The supermarket was in fact the endpoint of the U.S. government’s battle for agricultural abundance against the U.S.S.R. Our farm policies were built to dominate, not necessarily to nourish — and we are still living with the consequences.

Rethinking meat
How can we convince people to change their relationship with meat? Melanie Joy has been grappling with this question for a long time. To answer it, she takes us back to other points in history when new technology helped make social change palatable. She digs into how the invention of the washing machine and other household appliances, for example, helped make feminism easier to imagine. Then, she looks to the future, at our latest meat technologies — plant-based meat and lab grown meat — and asks: Could they make it easier for us to move away from meat altogether?  Further listening and reading:  Joy’s books, Powerarchy: Understanding the Psychology of Oppression for Social Transformation and Why We Love Dogs, Eat Pigs, and Wear Cows.  Vox’s Ezra Klein interviewed Joy for an episode of The Ezra Klein Show in 2018.
