In this article, we propose to understand Occupy Wall Street’s political rationality as a protest against a situation of indebtedness that constitutes today an “existential condition” for a majority of Americans, and as an attempt at building bonds of solidarity between debtors by highlighting the structural and collective dimension of this shared condition. We thus analyze the discourse and strategies of a militant group born out of the OWS sphere: Strike Debt. By intervening at the level of affects and representations that sustain the legitimation of debts, its action aims at transforming default into a political gesture capable of toppling the power of the financial industry.
