In contemporary urban areas, a growing ‘generation rent’ is finding shelter in expensive and precarious private rental housing. Tenant organisations and legislative initiatives have been pushing to improve housing conditions for renters, yet have been met with strong resistance. Intense policy and academic debates have ensued. This paper delves into the discourses used by dominant actors involved in legislative changes affecting the private rental sector in Catalonia and Spain. Through a critical discourse analysis of the positions of governments, opposition parties and landlord organisations, we identify three main arguments employed to limit or contest ‘post-neoliberal’ measures favouring tenants: ‘the vulnerable landlord’, ‘the counterproductive effects’ and ‘the violation of property rights’. Each of these arguments is placed under theoretical and empirical scrutiny, revealing important weaknesses. By unsettling dominant discourses, we contribute to advancing the terms of the debates and sketch out the coordinates for a counter-discourse informed by critical theory and the interests of renters rather than rentiers.
