During the time that the debt remains unpaid, the logic of hierarchy takes hold. There is no reciprocity. As anyone who has ever been in jail knows, the first thing the jailors communicate is that nothing that happens in jail has anything to do with justice. Similarly, debtor and creditor confront each other like a peasant before a feudal lord. The law of precedent takes hold. If you bring your creditor tomatoes from the garden, it never occurs to you that he would give something back.
