HOST: But back in the day, and I mean WAY
back in the day, everybody did this.
Cultures the world over had animals and crops
to trade with each other. And that’s what
made the economy work.

The simplest form of trade is barter. For
instance, you have a cow but you want a couple
of sheep. So you find someone with a sheep
who wants a cow. You trade; you’re happy,
done deal. People bartered their animals or
anything of value: food or cloth, or building
materials, or even the labor to build a house.
