The automation argument can be answered very simply - allow people to retire earlier.
When the state retirement age is heading every upwards towards 70 it's very difficult to take the 'automation' argument seriously at all. When it gets down below 50 there may be a case.
But of course that isn't the argument for Basic Income at all. The desire for Basic Income comes from a certain section of the middle class who want a 'passive income' they can use to buy new Wellies for Glasto. All the 'justifications' raised are smokescreens to hide the real reason.
What they forget is that the reason the rich are detested is because they are seen as not having earned their income.
