Because gunners in med school treat it like it's the pinnacle of medicine that they have to get into and yet it's nowhere near as prestigious as neurosurgery, cardiology, or oncology ,where you're actually making complex life and death decisions on a daily basis instead of replacing a joint/fixing a plate hundreds of times throughout your career until you retire. Let's be honest. Orthopods get all the love by naive medical students because of the heavily inflated salary, cush hours, and celebrity-status in the hospital, not because they have any sort of genuine interest in the field (only very few do). The same exact thing can be said about dermatology.
