psychology of debt
Greaber in a nutshell:
Unfettered debt creates a world of all against all, unprincipled cold-blooded calculation with outbursts of inexplicably vindictive cruelty. The motivation is the debtor feeling he has done nothing wrong to find himself in this trap, the frantic urgency of having to convert everything around him into money in order to escape ti, and rage and indignation at having been reduced to the kind of person who does this thing.
Seems to me that this is like drug addiction.
