That said – one thing that has made me change my mind recently, though, is that UBI might serve as a buffer against the profit motive taking over everything. Increasingly it seems like other value systems are being overtaken by the desire to earn money. By "other value systems" I mean a huge variety of things that aren't driven by money: living a non-materialistic lifestyle in line with numerous religions, mastering a centuries-old craft that doesn't have much market demand, being a philosopher/thinker not defined by participation in academia (or the market), and so on.
Part of the growth of the profit motive can be attributed to the general precarious economic situation, unpredictability of future jobs, etc. But it's also because there are fewer and fewer cultural institutions that make up the ecosystem, because no one wants to make that bet anymore. Everything seems to default back to monetary/professional success, whether that be the "creator economy" or getting a professorship at a top university.
So I do wonder if UBI would be a mechanism for encouraging people to say, "I can count on making a basic living, so I'm going to study XYZ art form and become great at it."
