By commonwealth, I mean the wealth that no one has made, or the wealth that practically everyone has made. It’s the very basis of the concept of income, because income is the maximum that you can consume today and still be able to produce and consume the same amount tomorrow – that is, maximum consumption without depleting capital in the broad sense of future productive capacity. Using with maintenance and replenishment is an important idea in economics. Let’s start with this phrase: “sustaining our commonwealth.” By sustaining, I don’t mean preserving inviolate I mean using, without using up.
