Hi, I'm Ryan Grim. Welcome to Deconstruct it. When we think about the concept of solidarity,

it's hard not to get Pete Seeger immediately stuck in our heads. Solidarity forever,

for the Union makes us strong.

Though curiously, in the West, it's an idea that has stayed strictly siloed to the labor movement, but why?

And does it have to be that way?

After all, it's an expression of a truly human universal impulse.

A new book called Solidarity, the past, present, and future of a world-changing idea,

tries to unpack why we have generally ignored the notion of Solid solidarity and how our world can be made a better

place by embracing and enacting solidarity.

It's co-written by Leah Hunt Hendricks, who co-founded Solidair and also a way to win, which are both networks of donors trying to rethink

philanthropy, an author and documentarian Astra Taylor, who co-founded a debt collective,

the first union of debtors.

Astra and Leah, welcome to deconstruct it.

It's great to be here.

Thanks for having us.

And Leah, thank you kindly.

So happy to be here.

So let's talk about solidarity.

You mentioned in the book that it has a really interesting

root coming from a debt that is kind of collectively owed just by virtue of being born.

Talk a little bit about where this concept of solidarity,

this idea of solidarity came from in the ancient world.
