Today and throughout history, a mere six competing stories of ownership have dictated how everything in the world is distributed. As resources have become scarcer, everyone from American homesteaders and ranchers, to tech leaders and consumer brands, have created ways to impose their own preferred ownership story in a world where what it means to “own” something is constantly evolving.

We speak with Michael Heller and James Salzman, two of the world’s leading scholars and authorities on ownership, and co-authors of the book Mine!: How The Hidden Rules of Ownership Control Our Lives. They explain to us how the rules of ownership change in every generation, and how those changes reveal the true brand landscape, the role of business, and most importantly, a society’s shifting values.
