Old for new, this for that, goods for cash. Exchanging goods, services, skills, land—even people—has pushed the world toward its current state. And, for better or for worse, it underpins our modern world. The latest issue of Makeshift Magazine explores the intricate labyrinth of trade around the world. But we're not talking about Wall Street here. We're talking about inventive exchanges and backroom deals. This latest issue features everything from analog wire transfers in the Middle East, organ swapping in China, and bustling exchange in the Nakivale refugee camp.

I had the opportunity to sit down with the community organizers behind the Trade School Toronto (TSTO) and write about this growing global network of learning spaces that run exclusively on barter. Anyone can teach a class and students attend with barter items that the teacher requests. Two-hour classes run the gamut from urban forestry to learning the 8-count lindy hop. And you can learn it all for the price of a vegan meal, a song, a baking sheet, or even just the simple promise to try swing dancing again. TSTO and its equivalents around the world is a manifestation of the move away from traditional educational systems to alternative, more accessible learning models.
