I'm going through a midlife crisis right now where I'm actively rejecting the decisions I made since 2000. I had a falling out with professional programming last year and am looking into the gig economy. I'm not going to buy new anything if I can possibly avoid it. I'm trying to turn my attention from external expectation to what I felt was my life purpose when I graduated college in 1999.
Which will basically amount to finding a way to earn roughly $1000 per month doing whatever it takes and then using the freed up time to work on inventions. I'm hoping to resurrect my blog and write about progress or my thoughts on tech rather than devolving into my usual diatribes about politics and how the world has generally gone the wrong direction. My acquaintances are concerned about me, and rightfully so, but I just don't care to live someone else's life anymore.
I think you're right though, that when basic needs are met, most people want to work on their calling whether it be art or recreation or simply being human. Which looks a bit like how the aristocracy lived in the Gilded Age over a century ago. There's no reason why we can't have that level of affluence today for every single person by letting machines do the labor, or by taxing profits on that labor and providing cash to all via UBI.
