This article is the product of prolonged wrestling with the question of how heritage professionals and researchers can facilitate and sustain public agency in caring for heritage in the UK during austerity without exploiting volunteers or devaluing professionals. It offers critical perspectives on efforts made to democratise heritage in the UK by increasing public participation through a critique of neoliberalism and the rise of neoliberal approaches in the heritage sector. It argues that the adoption of neoliberal approaches, such as crowdsourcing, that profess to democratise yet reinforce existing power structures, is the inevitable result of insisting on protecting material culture from harm, despite the continuing accumulation of more 'heritage'. Drawing on critical perspectives on participation from a number of disciplines, it is suggested that efforts to increase public participation in heritage cannot hope to avoid exploiting volunteers, devaluing professionals and marginalising traditionally underrepresented demographics unless they also let go of the perceived need to protect the materiality of the past. Drawing on Sarah May's archaeology of contemporary tigers, this article argues that the application of endangerment narratives to heritage reinforces uncritical understandings of both heritage and volunteering that preclude heritage from fulfilling its potential function as a contemporary social process.
