Marriage customs have undergone many profound changes in the past few centuries. Contemporary American brides and grooms don’t meet for the first time at the ceremony, and the bride doesn’t come attached to a dowry of livestock from her father. But while we’ve left many antiquated customs behind us, one aggravating convention holds on: the wedding gift. Doing something nice for your friends is, of course, lovely. Yet as currently constituted, the marital gift exchange is a barbarous relic: wasteful, unfair, and inefficient. It’s time to do away with the registry and this silly tradition.
