Exactly.
Most instructors have to work out in the elements, in a sport that the resorts themselves declare is "inherently dangerous" (but don't give battle pay to instructors), where the "professional" has to cover the costs of equipment (including helmet, boots, skis, boards, clothing) and certifications (which benefits the resorts), not to mention gas/tolls/food-- all for an insulting pay rate and a chance to stick one's hand out groveling for tips.
It might've worked back in the ski bum days, but seriously, who in their right mind thinks this is a good deal anymore? What kind of other "professionals" put up with this? Calling oneself a "professional" while groveling for tips is just a really bad joke- a joke on the instructors.
