I cannot reconcile your inclusion of greed while omitting fear. Those with income insecurity or food insecurity might be driven more by fear than greed. Instead of greed, which assumes you know the motivations of everyone, I would use productivity as a driver, though you might argue it is too aligned with human ingenuity to be added to your list. However, human ingenuity does not have to result in productivity improvement. Humans strive to leverage their time, ingenuity, resources to maximize the value produced by their work. If you take population growth as a constant, productivity is the primary driver of growth.
