This article analyzes the collective experiences related with sectors that suffered exclusions and inequalities in Argentina from 1995 to 2019. The study of the ways in which organizations resolved a series of dilemmas (of the agent and the actor) allow us to identify three phases. The first one took place from 1995 to 2004); we call it “phase of the unemployed movements”. The second one occurred between 2005 and 2011; we call it “phase of socio-political organizations”. And from 2011, the third one occurred; we call it “phase of the popular economy”. These phases show how similar social subjects can be configured as different political subjects. In addition, they contribute to understand the way in which a new actor was formed in Argentine politics.
