When I make an interest-free loan to you, I’m trusting you and giving you a gift at the same time. This interaction increases the quality of our bond and strengthens the community. Just as you wouldn’t charge your husband interest on a loan, you don’t charge a tribe member. Strangers, on the other hand, are not to be trusted. Going further, strangers don’t deserve the bond that the gift brings. It would turn the stranger into a tribe member, and the tribe is already too big. If I loan money to a stranger, I’m doing it for one reason: to make money.
