For the Western world, the challenges of the 21st Century are numerous, from climate change’s effects on food production and coastal cities to underfunded social safety nets to automation’s impact on the middle class. To handle such costly problems, government intervention will be required. Government intervention, however, always comes at a cost to either individuals or corporations. To determine who should bear these costs, scholars and experts should turn to notions of fiscal citizenship – the social contract between the state and private parties through taxation and the provision of goods and services. By applying principles of individual fiscal citizenship to corporations, which have traditionally not been included in notions of fiscal citizenship, a strong case emerges for corporations to bear the costs of these impending 21st century harms.
