I addressed this in other comments, I only want that a normal (full time) job pays for a living, I did not want to discuss all kind of edge cases and so it may not apply to your example. But if working at an ice cream shop is sufficiently easy to learn within a few days and the kid does all the same work including cleaning up and what not, how would you justify paying less than to a regular employee doing the same work and having to live on that income?
