If those were to happen, 80% of working people would be left to live in shanty towns and make do however they can, if they can.

Unless we're talking about Star Trek robotics that can do anything, the core activities like mining, farmimg, and so on would still be from the 10-20% of workers, even more underpaid because of the competition with the other 80% for those jobs.

Plus a number of craftsmen, chefs, servants, sex for hires, etc. catering to the elites.
