We can definitely expect the bottom 10% in your example to do "higher value" work, once their currently meager work is automated. For once they can become supervisors of robots doing the same work they do today, since they have experience and can provide guidance to the robots. Also, they can transition to work that benefits from the human interaction standpoint, such as elderly care. They will need some training, but not at the level that they can't absorb. As the population age, healthcare workers will be the single most growth segment, that robots cannot completely replace. Last but not least, many of the same "bottom 10%" are capable of getting higher education and get truly "higher value" jobs.
Bottom line is, AI and automation can cause short term pain, but the upside is enormous. Successful countries will be those that can manage that transition.
The bottom 10% are usually those with disabilities like autism. Many of them really aren't capable of getting higher education. I have a 21 year old son with autism that has never even learned the multiplication tables (as a single example) despite our spending tens of thousands of dollars on private tutoring and other training outside of his schooling. He works a low level job at the airport that he enjoys. But, realistically, it is at the upper limits of his abilities. He is far far away from being a lone case. I really don't think many of the bottom 10% can be trained into higher value jobs.

This sounds great in theory, and I fully agree, but the system of compensation and wealth distribution will need to be turned upside down for that to happen.
The value created by current and future automation will somehow need to be captured and distributed to people whose financially profitable jobs are going to be replaced with unprofitable, but socially-beneficial work, there's really no way around it. Those people will still need to be fed, housed and have access to at least basic luxuries.
Furthermore, what do we do in a future "ideal" world where robots and AI are capable of providing basic necessities to sustain every human alive? Capitalism would likely break down one way or another, with branching paths that either take us to an utopia or a nightmare dystopia.
Bottom line is, AI and automation can cause short term pain, but the upside is enormous. Successful countries will be those that can manage that transition.
