"Enough" names what orthodox economics cannot measure. The discipline's organizing question for three centuries has been how to produce more; it has no vocabulary for the quantity that would be sufficient. Raworth's doughnut makes enough thinkable by giving it visual form: the bounded zone between a floor below which deprivation begins and a ceiling above which further accumulation adds nothing to well-being while imposing costs on others and on the planet. Enough is not a fixed quantity — it varies with population, technology, and ecological conditions — but it is a bounded quantity, and naming it is the framework's most radical move.

In a system whose success metric is expansion, there is no stopping point, no threshold beyond which further growth would be recognized as excess. Every increment of GDP is counted as progress; every decrease is counted as failure. The variable is always
