“A promise/obligation which cannot ever be fully met is at the very base of the banking system. When one puts money into a bank, the bank is obliged to return the money on demand – but we all know that, while the bank can do this to some of the people who deposited money, it by definition cannot do it for all of them.
…
Debt is an instrument with which to control and regulate the debtor, and, as such, it strives for its own expanded reproduction.”
― Slavoj Zizek, Trouble in Paradise, From the End of History to the End of Capitalism
