From an ethical/moral point of view, a UBI makes total sense; if someone doesn't want to work, why should they be forced to? Problem is we still haven't seen a single country implement UBI. Why is that? Wouldn't people favor "not being forced to work" and vote for it? I'm not an economist but perhaps the math doesn't add up. It might be that "being forced to work" makes the overall economy healthier. For instance, if you're a professional athlete, you have to put in the hard work no matter what, if you want to perform the best, sometimes even against your own will. If you look at a country's economy as a pro-athlete, it also has to put in hard work to stay at the top. I'm not saying that should be the way we should live our lives. In fact, most people are perfectly happy not being pro-athletes and not having to put in the hard work. There's also the argument that if you have a whole country willing to decide what they want to do (UBI), there could be a boost in innovation. That's certainly possible, but again, any boost in innovation requires hard work. And certainly the ones forced to do the hard work would outperform the others. But then again, that's a form of slavery.
