Of course, whether it'd actually be better for everyone or it'd actually be stable is another can of worm entirely.
Fuck that
Post-scarcity and post-work society takes a formal effort for people to find purpose. It requires that we really try to find things that are valuable and that we enjoy.
But I do not believe we will live, as a society, to see the end of scarcity or jobs. We'll kill ourselves way before we get to that point.
You're right - some may "do nothing", but the kind of people that would "do nothing" if nobody were forced to work to live are the kind of people, by and large, that do just enough to get by.
Even if we instituted a generous UBI, people would still have to work to live because landlords/real estate speculator aren't going to let all of those money slosh around freely - they want theirs too.
A childhood of workin outside, whether that's working with animals or working in the soil, teaches entirely different lessons than living in video games or social media and eating food that magically shows up on grocery store shelves.
I obviously don't know you or your children and am picking on video games and social media only in a general example of many children's common experiences today.
My childhood was spent on a farm, we all worked or we didn't eat. It was fucking miserable. I wouldn't wish that on anyone who doesn't want it.
