That's one of the reasons why putting people from highly unemployed groups in jails is not the right long term solution. Eventually you won't even have jobs for jailers as a side benefit.

You might always imagine that eventually all people end up in jail that will get pretty relaxed till then and robot jailers will become just become security beneficial mostly to prisoners since there won't be much people outside only industry and ai-s that will have to be reasonably protected from descendants of monkeys in mutual interest of all involved. That would be cool idea for dystopian/utopian short story or novel.
