Any form of abundance-based economics is necessary though not sufficient to solve any global issue(s). Accepting the premise of scarcity-based economics will automatically result in the failure of any creative global solution, such as “green capitalism” or “democratic socialism.”
Abundance-based economics assumes that Earth is one component of a solar system and universe that is an open system of systems to be harvested. Scarcity-based economics, whether rooted in capitalism, socialism or barter assumes that Earth is a closed-loop system to be controlled.
