> There actually isn't a finite set of resources when we're talking about human capital

Ever heard of something called a budget?

Teachers, aid workers, doctors, and others need to get paid. Their suppliers need to get paid. Infrastructure needs to be built.

All of that costs money.

So what, there's only so much money? Or does money represent the amount of work people are willing to do?

My point is simply that the amount of productivity a given population can exercise is not bound to the amount of money in circulation.
