I wouldn't expect a small but steady income to be enough all by itself, but it will put people closer to retiring. When combined with some savings, I'd expect some people would choose to retire earlier than they would if they didn't have it.
I do support UBI, but I also expect that it would have complicated effects.
Right, but wouldn't that be similar? Obviously there are going to be people who are going to say "screw it, I'm going to live like this" on a basic survival-wage UBI, but I doubt a majority would want to.
