Gross domestic product (GDP) counts transactions. It does not count what those transactions cost, and it does not count what never changes hands. That distinction sounds technical, yet it shapes what a nation chooses to protect and what it chooses to spend down.
An engineer would describe GDP as a sensor that measures throughput and ignores the condition of the system producing it. A measure built that way will reward depletion, and a society that steers by it will, given enough time, consume its own foundations and record the result as growth.
