Traditional economics is built on the assumption of self-interested individuals seeking to maximize personal gain. This is far from the whole story, however: sharing, caring and a desire to uphold the collective good are also powerful individual motives. In a world wracked by inequality, social divisions, and ecological destruction, can we build an alternative economics based on our mutual co-operation? In this book Chris Benner and Manuel Pastor invite us to imagine and create a new sort of solidarity economics - an approach grounded in our instincts for connection and community - and in so doing, actually build a more robust, sustainable, and equitable economy. They argue that our current economy is already deeply dependent on mutuality, but that the inequality and fragmentation created by the status quo undermines this mutuality and with it our economic wellbeing. They outline the theoretical framing, policy agenda, and social movements we need to revive solidarity and apply it to whole societies. Solidarity Economics is an essential read for anyone who longs for an economy that can generate prosperity, provide for all, and preserve the planet.
