All immaterial. Without a basic income, the wealthy corporation owners who've invested all this money in automation will inevitably see their consumer base shrink and then disappear.

And all the automation will have been for nothing. The machines will have to stop working when the money stops flowing.

No company benefiting from full fledged automation would have any motivation to hide all of its profits and refuse to pay some taxes into a UBI fund.

Obviously the taxation isn't going to be at a point where it ceases to be profitable for companies to exist -- it's going to be at a level where companies can still make unprecedented profits due to the unprecedented level of automation -- but with that little bit being redistributed to consumers, the companies are guaranteed consumers for life.

Mass automation and UBI are two sides of the same coin. They form a symbiotic relationship that results in a society where work we don't want to do is done by machines and humans are free to choose how to live their lives.

Without basic income to compensate the unemployable humans -- which will be damn near all humans -- the automation will be for nothing.
