Advancements in AI and the gradual digitization of society could one day lead to a world where earning a living is inessential to living a decent life.
Earning a living is essential right now. Outside of the few who are so independently wealthy that other people earn their living for them, everybody has to earn a living some how.
In China, there are wealthy who are so rich that servants/slaves feed them and wipe their behind for them. In the past, some of them would close their hands (make a fist) for such a long time that their fingernails grew right through thei hands. This was a sign of great wealth in China in times past.
But, even then, most of these wealthy people had to breathe for themselves. So they worked for a living, even if it was only breathing.
If we want to get this far with all of society, robots will have to become advanced far beyon what they are today. And they will have to be built in ways that they will never want to rebel.
