All scarcity problems since 50 or even 100 years ago are artificial self inflicted constructs.
We are post-scarcity the moment we simply decide to be.
The reason we haven't and wont any time soon is property rights and everyone who has anything to lose in any redistribution or any change to future distribution.
It wasn't that long ago that 30% of children died before age 1. Imagine having a baby and there is a 30% chance it is dead in a year? That is almost all of human history.
The complaint will remain constant no matter what. If everyone owned a BMW some people would complain there is this aristocratic class that has a 7 series while the peasants all own 3 series and that we need to make things more equal.
We are so equal that the richest man in history and a homeless person practically have the same smart phone.
There is only one possible outcome where everybody wins and that is capitalism becomes so incredibly good at eliminating inefficiencies that all possible work is automated away, leading to the collapse of capitalism itself since it depends on continuous consumption which depends on disposable income which won't exist because there are no jobs.
I'd really like to believe this is the point where the world evolves into post scarcity where there is no economy because there is enough for everybody and no need to economize anything. Realistically, the corporations will most likely literally invent new economies out of thin air based on nothing just like they did when they conjured up nonsense like copyright.
