Gifts create bonds. They create reciprocal connections between individuals, they result in interaction between people and thus are highly personal. There is an unspoken obligation of the gift receiver to return the generosity at some point in the future in some way, shape or form, but there is no set date or value for the future interaction. Researching various gift economies, it was found that those who perform the most favors and give the most gifts to others are often the most powerful because they have set up multiple reciprocal favors that they haven’t called in yet. Even if they never call in those favors, the gratitude from the recipients adds up to doing something good for the world.
