Yes and no. Given a specific definition of "not impoverished", there is a threshold of energy availability below which energy is fundamentally limiting towards achieving that definition. Above that though, there are other factors, and IMO, there are only two other fundamental ones: cognition (the capacity/time to perceive and manipulate the world by directing energy towards goals) and social capital (society allowing you to direct energy towards your goals, and/or supporting your goals through application of their energy and cognition).
