So let's say where 10 people were needed to do a task, now (due to automation or what have you) you just need 1. What should you do: a) since the same thing is produced with 1/10th of the labour, reduce work hours, implement UBI, etc, or b) invent 9 bullshit jobs to keep everyone busy and working their god-ordained 8hrs a day to "deserve" their existence. Option b) is the answer that capitalism gives, but it's not the right answer in an objective sense.
