I think this may be part of a larger problem where fewer of our rewards are truly meaningful. As society gets richer many things get much easier to acquire and thus less meaningful; my grandparents' generation have stories about how big a deal it was to get a whole banana.
As we mindlessly try to move up the ladder of value, success leads to buying cars and houses as status symbols and trying to fake that it feels like a reward. Which is turn leads to defining success as having the most fake rewards, and builds a vicious cycle.
Figuring out how to organically motivate and reward people is one of the biggest questions for me as we approach a post-scarcity society. Things like UBI can manage the resource issue but they don't manage the motivation issue.
How do we figure out better what we value and use that to drive us toward our best selves?
This is indeed the issues and we can already see that most people will avoid work (including the things they enjoy) to rather be entertained through consumption activities. The UBI will likely increase this substantially. What do we do when we don't have to do anything? Nothing, by all observation. People want to retire to a tropical island and sip Daquiris and if they can do that at 30, they are successful. The masters of old would be ashamed at how frivolously we live life these days.
Daiquiris, oddly enough, are one of humanity's most-difficult-to-produce inventions. Both sugar cane production and fruit production rely heavily on exploitative labor practices and unsustainable resource use. (At least we're pretty good at ice.)
If we can get the system to the point where it sustainably automates daiquiri production, we'll really be at a point where everyone can sit around drinking them if they really want to. I like a good daiquiri every once in a while but that seems pretty boring.
learn something new every day... I have never had one ;)
