Imagine it is 2025 and that years earlier, in the wake of the financial crisis of 2008, a global uprising had birthed a post-capitalist world in which democracy, equality and justice are truly served. In a thought-experiment of startling originality, world-famous economist Yanis Varoufakis blends an ancient form - The platonic dialogue - with speculative fiction to offer a glimpse of this alternative reality. Through the eyes of three characters - a liberal ex-banker, a radical feminist and a maverick technologist - we see what would be needed to forge such a world, one without commercial Banks or stock markets, where companies are collectively owned and housing and income are guaranteed, but also at what cost. How to balance freedom with fairness? How to generate wealth while protecting the planet? How to encourage the best of humanity without unleashing the worst? As radical in its form as in its vision, another now shows how our answers to these questions shape our society, helping us confront the one question that underpins them all: how far are we willing to go in pursuit of our ideals?.
