Also I think a side effect of Basic Income will be greatly increased quality of jobs, because I'd imagine for a lot of jobs, making them less shitty is a lot more attractive for the cost than a higher wage.
For example, a lot of service jobs have polices of putting up with extremely obnoxious behaviour, because it marginally increases revenue at the expense of the employee's sanity, which is effectively free. But if you're not quite as desperate for a job, you're much more able to price that in, and choose to work for less at the restaurant next door, that lets you tell jerks to GTFO.
All work can certainly be fulfilling, but more because of the reasons I described (it's a means to an end) than the reasons you're describing. Certainly, people shouldn't be forced to take particularly degrading jobs when they don't want to in order to survive. But do they find it degrading, or do you? Those are two very different things.
It's impossible that there are enough people in the world passionate about garbage collection -- allocated perfectly across the correct geographic regions, mind you -- to fill all of the available positions.
And you base this claim on what?
I'm not saying it's likely, but it's certainly not "impossible."
Where do you read me assigning more value to STEM work? You're totally injecting that into what I wrote.
On the contrary, I'm saying that all work can be fulfilling, not just STEM work. But all work can also be degrading if it forces people to compromise themselves unreasonably.
