We live in the XXI century.
We have inherited our civilisation from Sumer, Akkad, Babylon, Persia, Greece, Rome, Khalifat and the West.
Our technological progress is enormous. Global economy has never been as strong and productive as today.
We can afford food for everyone, home for everyone, opportunity for everyone and dignity for everyone. This is what 'living within our means' means today.
Anything below that is artificial man-made scarcity.
