Applying your thinking about human nature to my situation, I retired when I decided not to work any longer, though I was perfectly capable of several more years of productive work, and, receiving an income of a state pension, almost a UBI, it is paid to the rich and the poor alike, with no need to work at all, and not expected to offer anything in return for the rest of my years, should I be sent back to work to justify my place in society?
I think
@Bletchleyite has covered that one for me. I'm not talking about retired people here: I think there's a broad shared understanding that, retirement is something that people have earned by working through their lives. I would however apply the logic if you're choosing to take
early retirement. As a general principle (I don't know the details of your situation), I would say taking early retirement is fine if you have built up the savings/made the pension contributions/etc. that you can completely fund your early retirement yourself, but it's not fair on other people if you're expecting people who are themselves working until the actual retirement age to fund your lifestyle choice to stop working below retirement age.
Maybe I'm a bit naïve, but UBI may bring out the best in people who are ordinarily prevented from reaching their true potential, simply because the current system is so rigid and doesn't suit everyone.
No qualifications? You're written off as too stupid, didn't pay enough attention, didn't work hard enough etc. Took a wrong turn in life and perhaps you have a couple of minor convictions? Again, written off.
I don't think it's right to write people off in that way, and I wouldn't approve of that. But at the same time, I think if you want to bring out the best in people, you do have to have a culture that sets expectations. By analogy, think what makes the best teachers at school: In all my experience, the best teachers always encourage - they don't put you down - but that's not all: They also set expectations and gently push you to do your best. In fact, as I'm writing this, I'm thinking of two adult education classes I attended earlier this year. Same subject and similar courses but different organisations. In one, the teachers were always encouraging and positive, but no more. In the other, the teachers were just as encouraging and positive AND at the same time they were very clear about stating what work they expected people to put in outside classes etc. In other words, they set the expectations. No prizes for guessing which course had people generally achieve the most. Funnily enough, I also noticed that the course in which expectations were set also had a lower drop-out rate and people seemed more satisfied at the end of the course.
I know analogies are never perfect, but to my mind, UBI is a bit like offering the encouragement/support but without any expectations. Something like the guaranteed job which I'd favour as an alternative is more like, offering the encouragement/support AND setting the expectations of what people should do to help themselves/contribute in return.
