Neoliberal market logic positions youth as either commodities produced and marketed by private institutions or consumers for whose business those institutions are competing, a paradigm that narrows pathways for youth participation in civic and political institutions by restricting youth agency to participation in markets. However, youth organizing groups recast what we imagine as the public domain, how public institutions are governed, and who takes part in this governance.
