Economics is the study of scarcity. In a world with limited resources, how do we maximise the production, consumption and transfer of wealth for the best possible outcome? Times change, and change dramatically. In 1800, the world's population was less than 1 Billion. Resources were abundant, what we needed was scarce. It is now at 7.6 Billion, and some estimates see us topping out at around 11 Billion. Parts of this explosion has come from massive changes in how much stuff we can make, and how well we can deal with death and diseases. The question of how can we grow enough, shifts to what is enough? The mindset is completely different. Saying I have enough, allows you to shift your attention to others. Rather than production, consumption, and transfer... study shifts to sustainability, custodianship, and interdependence. Learning to thrive. Learning to share. The study of Sustainable Abundance.
