Sure, but an apprentice can learn the basics to be useful on the job in a couple days.

That's not the point anyway, working entry-level retail is pretty much a 0 stakes job — quality has been mostly engineered out of it. Even a basic cabinet assembly job requires some quality control. Some people do not want to do anything of quality.

IMO we'd all be better off if people had a universal basic income and these people could spend more time finding something else to do with their time.
