The definitive discourse with Noam Chomsky on the defining characteristic of our time - the deliberate concentration of wealth and power in the hands of a select few. Chomsky unpacks the principles that have brought us to the crossroads of historically unprecedented inequality - tracing a half century of policies designed to favour the most wealthy at the expense of the majority. "Requiem for the American Dream" is profoundly personal and thought provoking.

As our understanding of it has increased so has our reliance upon it, and today we are on the brink of a new breakthrough, because if we can understand the secret of electrical superconductivity, we could once again transform the world.
