It makes no sense, though. Who is going to clear tables and wash dishes? Who is going to pick fruit? I picked fruit as a teenager. It sucked. I hated every minute of it, but it has to happen. Your suggestion seems to be making it suck more than it has to in the name of what... motivation? Why not make it possible for every member of our society to live a decent life, even if they happen to not have the necessary faculties (not to mention money, support and time) to be an engineer?
