Very interesting historical and anthropological overview of what people do with debts. I only knew debts from taking up money to buy a house or a car or from news of companies going bancrupt. Graeber shows its rich history, its connections to gifts, relations, slavery, honor, military and fair markets.

Most memorable for me were the sections explaining that our idea of freedom is derived from a roman citizen to their slaves and thus freedom being something you can have or loose as well as being do do whatever is permitted with ones property.
