What makes capitalism different from most other economic systems in history is that it’s organised around the imperative of constant expansion, or ‘growth’: ever-increasing levels of industrial extraction, production and consumption, which we have come to measure in terms of Gross Domestic Product (GDP).29 Growth is the prime directive of capital. Not growth for any particular purpose, mind you, but growth for its own sake. And it has a kind of totalitarian logic to it: every industry, every sector, every national economy must grow, all the time, with no identifiable end-point.
