“Scarcity seems natural to us; water, food, land, these are all scarce in our world. So when something is not scarce we sometimes struggle to understand it. It is easy to assume that providing something to one person always uses up resources so that they cannot be used to provide something to someone else. But not every resource needed to realise economic, social and cultural rights is like that…”
I expand on this idea in a post on the Association of Progressive Communications website; Economic, Social and Cultural Rights: The limitless textbook.
