IN A SERVICEBERRY ECONOMY, I accept the gift from the tree and then spread that gift around, with a dish of berries to my neighbor, who makes a pie to share with his friend, who feels so wealthy in food and friendship that he volunteers at the food pantry. You know how it goes. In contrast, if I were to buy a basket of berries in a market economy, the relationship ends with the exchange of money. Once I hand over my credit card, I have no further exchange with the clerk or the store. We’re done. I own these berries now and can do with them as I like.
