Cymene and Dominic talk about hauling ice, champagne socialism and the mystery of Viennetta cakes on this week's intro. Then (16:07) we are joined by Troy Vettese, an environmental historian, and Drew Pendergrass, an environmental engineer, to talk about their bold and imaginative new book, Half-Earth Socialism: A Plan to Save the Future from Extinction, Climate Change and Pandemics (Verso 2022, https://www.versobooks.com/books/3818-hal). We begin with the value of thinking in impractical ways and how utopian socialists past like Edward Bellamy, William Morris and Otto Neurath inspired this project. We discuss how high growth expectations have bedeviled planning in the past and talk about the flaws in the utopia of automated luxury socialism. Is capitalism an inherently irrational system? Does planning have irrational tendencies too? We cover where the idea to make a game version of the book came from (https://play.half.earth). We move from there to what the Left could stand to learn from the tactics of the neoliberal revolution, the necessity of utopian imagination for mass organizing, how intellectuals underestimate the readiness of the working class for change and much, much, more.
