This seems like a case of "Is the cup half full or half empty?"
In any case, methinks your obsession with unemployment rate is one of the things that we must seriously reconsider if we really want to be objective about the merits (or lack thereof) of basic income (BI).
Let's get a bit philosophical here. One of the fundamental premises of BI is that it's OK for a substantial portion of a future society not to do anything that is traditionally considered "work". And one of the reasons we need to experiment with BI is to see whether or not this seemingly outrageous premise turns out to be correct after all.
Including the unemployment rate in your definition of "it can work in the U.S." is inherently biased against BI because it already assumes the opposite of one of the premises of BI. It's like trying to decide between theism and atheism using the Bible as your measuring stick. Regardless of what conclusion you draw at the end of the day, that competition ain't fair.
In order to make a fair decision, we'll need to go a little meta and ask, for example, about the total productivity of the society, the physical and mental well-being of its citizens, or something like that.
In any given economic system at any given time, there is a finite level of wealth to be shared by everyone participating in that system. (note: by 'wealth,' I mean things, not currency.) When people work, they produce things (and services), and this increases the total level of wealth within that system. When they do not work, they do not produce things, but they are still consuming things. Thus, people who do not work yet still consume in a given system reduces the overall level of wealth within that system, which reduces the level of wealth that everyone within that system can enjoy.
Thus, from a wealth standpoint, a system with less unemployment is preferable to one with more.
Proponents of basic income usually claim that when people are freed from the drudgery of working a normal job, they will be free to be creative, to take risks, to start businesses, and that this new productivity will compensate for the loss of productivity in the traditional system.
But that's all that is: a claim. It's completely worthless without some kind of data backing it up. It's akin to a preacher saying that God exists because he said that God exists. It simply has no merit.
So would the loss of productivity be compensated for by the increase in physical and mental well-being? I have no clue, nor do you, nor does anyone, because we lack data.
There is plenty of "work" that happens outside of the labor market. Some days I pay a babysitter to take care of my daughter; other days my wife has off instead and does the same job.
Once, my battery died and a paid a tow truck for a jumpstart. Another time, I was able to call a friend to get a jump instead. Both times the same service was provided.
The last time I moved, I paid movers to haul boxes. The time before that, my brother and I did the work.
Money in exchange for labor isn't the only way useful work gets done and counted. Some things will still get done even when people aren't paid to do them.
Do you consider advertising to be work? As in, people who work for Pepsi or Coke, convincing consumers to purchase their brand of sugary water over their competitors'. Is that producing wealth? Is society as a whole enjoying a higher level of wealth as a result of their work?
Or would our collective wealth (more broadly defined) be higher if those same people were creating works of art with their skills?
