Mainstream economics fails to grasp the nature of money. It is seen either as a 'neutral veil' over the operation of the 'real' economy or as a 'thing' - a special commodity. This book draws on neglected traditions in the social sciences to develop a theory of the 'social relation' of money.

In What Money Can't Buy, renowned political philosopher Michael J. Sandel rethinks the role that markets and money should play in our society. Should we pay children to read books or to get good grades? Should we put a price on human life to decide how much pollution to allow? Is it ethical to pay people to test risky new drugs or to donate their organs? What about hiring mercenaries to fight our wars, outsourcing inmates to for-profit prisons, auctioning admission to elite universities, or selling citizenship to immigrants willing to pay? In his New York Times bestseller What Money Can't Buy, Michael J. Sandel takes up one of the biggest ethical questions of our time: Isn't there something wrong with a world in which everything is for sale? If so, how can we prevent market values from reaching into spheres of life where they don't belong? What are the moral limits of markets? Over recent decades, market values have crowded out nonmarket norms in almost every aspect of life. Without quite realizing it, Sandel argues, we have drifted from having a market economy to being a market society. In Justice, an international bestseller, Sandel showed himself to be a master at illuminating, with clarity and verve, the hard moral questions we confront in our everyday lives. Now, in What Money Can't Buy, he provokes a debate that's been missing in our market-driven age: What is the proper role of markets in a democratic society, and how can we protect the moral and civic goods that markets do not honor and money cannot buy?

This book provides a comprehensive overview of historical and international debates on the theory of “labor money” or “labor notes.” These debates exist in a triangular context of market socialism, communism (community-based socialism), and local currency, joining numerous socialists, anarchists, and Marx and Engels. Labor note theory encompasses theoretical, ideological, and practical doctrines aimed at designing a fair and desirable labor-based market or non-market economy by reforming the monetary and credit system. This theory was considered an unfeasible utopian idea in the context of orthodox Marxism, which is typically based on a historical study of surplus value doctrines. However, this book eschews Marx’s critique of “labor money” that limits the debate regarding a concrete alternative society, and instead proposes practical and gradual approaches to social reform by scrutinizing the primary sources of labor money theories and practical experiences and reconstructs their theoretical relationships.
