Book excerpt: The current social security system is unwieldy, complex, unjust and unfit for purpose. It is a Gordian Knot that cannot be unravelled or reformed, which must be cut through and replaced by a system fit for the 21st century. Basic Income. 'a periodic cash payment unconditionally delivered to all on an individual basis without means-test or work requirement', is such a system and one that will redefine the relationship between the state, society and the individual. Annie Miller condenses her accumulated knowledge from over thirty years of involvement in the basic income debate into a short, readable form that makes basic income understandable to citizens worldwide. These essentials are a useful resource for opinion-formers and policy-makers, activists and citizens in the growing global basic income movement both during and after the Covid-19 pandemic.
