'Nowadays people know the price of everything and the value of nothing.' Credit has crunched, debt has turned toxic, the gears of the world economy have ground to a halt. Yet despite its failures, the same market-driven ideas are being applied to everything from famine to climate change. We need to ask again one of the most fundamental questions a society ever addresses: why do things cost what they do? Radical, original, nimbly argued, The Value of Nothing draws on ideas from history, philosophy, psychology and agriculture to show how we can build an economically and environmentally sound future.
