I also didn't say it can't, but I think the choice to make it optimal for SMB's, middle class, and upper middle class is an intentional one. I don't think that'll happen just by doing UBI. Hence I said, if you think it will then citation needed.
A: "Newer designs are safer."
B: "There is no evidence of that because they haven't been built yet."
A: "We're talking about the design here. You can see that it has these passive safety features which..."
B: "But there is no evidence of that because they haven't been built yet."
A: "Okay, then let's build them so that we can see the evidence."
B: "No, we can't build them because there is no evidence that it works."
UBI is purely theoretical. It does not exist anywhere on the planet in the form you're describing.
The US has engaged in UBI-like systems for quite a while, as have other countries.
UBI ascribes that everyone must get the benefit in order for the effects to be felt.
COVID incurred UBI-like payments, how these were used is worth studying, but they don't prove or disprove UBI. They certainly didn't improve the situation for small businesses, which is my point - if it takes a holistic UBI system to prove UBI and you're unwilling to figure out how to decompose it, then we'll never get it, and we're all doomed. That to me seems rather silly.
It is not a given that UBI will be a boon for businesses (big or small). Personally, I do think it will benefit large corporations, but it remains to be seen how small and medium businesses will fare -- and I think that largely depends on implementation details that need to be discovered. That much needs to be proven.
In order to prove some of the claims of UBI, countries are doing experiments and looking at specific effects that their implementations have in order to gauge UBI. Nobody is going to look a the monumental cost of UBI and fire a hope-driven-missile in terms of policy and economic risk, which is absolutely understandable. Finland and Ontario are putting out some tests, the inference they draw will largely depend on the questions they set out to answer. This is probably also informing them on how they could roll out UBI progressively.
What I was contesting was the absoluteness of this statement:
> This is why a UBI is good for businesses -- customers have more money in their pockets.
Nothing says that because people have money that they will spend it, much less where you want them to spend it. That has to be incentivized and we have to experiment with how to incentivize it.
