That's the toy model presented in introductory courses, but we have good of evidence that it isn't that simple. Or at least that we don't understand the dynamics very well. The resources used for other things do not necessarily help that much globally, they can just accumulate in less useful ways (i.e. trickle down economics is mostly wishful thinking)

The compelling impact of growth pointed out earlier (over centuries) was largely driven by the breaking of monopolies and increase in market access, as well as social change allowing more efficient allocation of resources.
