The underlying assumption of people who make automation arguments are that those whose job got automated out of existence will somehow be able to consume the profits of those automation (and thus enjoy life, rather than to work).

This is wrong, because the automation costed capital, and the capital owners who invested in the automation are the ones capturing the benefits (mostly).

Horses whose job got automated out of existence by cars don't get to retire lavishly - they got turned into glue. And so will the people, if such an event were to happen.
