Deficiencies in old age care are some of the most pressing human rights concerns in mature welfare states. This book radically challenges the ethics of viewing care as a tradeable commodity and introduces a novel framework for understanding and analysing social care through the concept of ailment. Providing examples from the British and Finnish welfare states, it demonstrates how ailment shapes societies from the micro to the macro level. Addressing the marketisation and financialisation of care, the authors bring to light increasing inequalities in care. This book argues that ailment is part of human life and society, and therefore the politics of care should begin with a politics of ailment.
