The US is a long way from “post scarcity”. It would means goods allocation would not be necessary anymore because all materials needs are more than fulfilled. (Atmospheric O2 is the only current thing with such characteristics I can think of…)

The notion itself is very contentious and hardly even fulfilled even in extremely optimistic science fiction.

My take is that a softer version of it could be achievable through clever manipulation of collective wants and needs through social media.

I think AI could help make aggregate mankind wants much more gentle on hard ressources like helping develop extremely addicting competitive sports or arts/activities so that almost everybody’s attention could be steered towards something more benign…
