I agree it only works if said person dreams of one day being on the cover of "Modern Plumbing" magazine, unclogging toilet's in front of a sold out crowd, and hoping one day adoring fans will one day ask for their autograph, and perhaps get an endorsement with a really good plunger or copper pipe company.
At same time, people who do go into plumbing/trades, usually start off as an apprentice, getting paid little to start with. People take non-paid internships in a variety of fields. So the analogy of the beginner working for peanuts is not without comparisons.
