Agreed, and the efficiency

The menial workforce would be much more efficient if it was operated by machines. The janitor of the now should be the engineer who comes in once in a while to repair the robot janitor, thus eliminating the working dangers or injuries to the human. Child labor laws would lose their anti-child labor basis of work-related injuries (the sweatshops of the old days) in favor of an education-based approach to support working children (intellectual labor). Kind of like how they teach the educational value of volunteering in public schools, except they get paid.
