"Who will pay for all this?!" is the usual outcry. Ignoring the very premise that automation has taken over the role of producing all this. Its a circular argument that has roots in the Protestant Work Ethic (independent of Capitalism) where "If I have to work, they everybody has to work dad gum it!"
In the US, that's going to be a difficult sell. States threatened to secede over the ACA and that was nowhere near as "socialist" as a universal income or right to food and shelter would be.
It could happen, but it seems like it would take a serious social and political upheaval, and the winds currently seem to be blowing in the other direction entirely. I hope it doesn't take something on the scale of the Great Depression to bring it about.
And before anyone calls that hyperbole, I don't see how refusing to provide some sort of garunteed welfare that provides food and housing is not "if you're poor you are gonna starve" in a system where access to food and shelter is tied to your income
How often has automation in the past led to the unemployed leading lives of intellectual pursuit and luxury? Never. Typically those made surplus to requirement are left to scrape by in meager poverty, as has happened in the American rust belt and Appalachia, because automation has lowered their value in society to be barely worth the cost of keeping them alive.
We need to prepare for that, rather than hoping for a utopian, post-scarcity fantasy that isn't going to happen.
