Or maybe they won't employ humans at all because robots will be able to stock the shelves and flip burgers for <$15/hr. At least sooner than they'll be able to for <$7/hr. Also some jobs will just go away, like grocery baggers (mostly) did. Which customers liked and was a good entry level job for teenagers. There are a lot of factors to consider and have to be careful about unintended consequences.
