When a farmer grows wheat, the act of growing it generates wages, rent, and profit — income that constitutes demand for other products. The circuit is self-reinforcing: production generates income, income constitutes demand, demand motivates further production. This is the actual Say's Law: a claim about the aggregate relationship between production and income in functioning market economies, not the caricature that every individual product automatically finds buyers. Understanding the circuit — its operation, its disruption, its re-establishment — is essential to reading the AI transition as an economic phenomenon rather than merely a technological one.

The circuit's precision is what makes it analytically powerful. Say was not claiming that overproduction of specific goods was impossible — he was a cloth manufacturer who had witnessed business failure directly. He was
