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.
But people are greedy for power and to have power, someone must be subservient. We have enough food and there's no need for wars.
Yes you are right! Your reply reminded me one of my favourite quotes from 1984 by George Orwell - I shared it in a post https://steemit.com/economics/@moneytree/george-orwell-on-austerity-and-war
George Orwell was a great thinker and many of the same problems we have today are the same ones from years ago.
Totally agree!
