No. Because for most pros competition is NOT their vocation, teaching is. No one was paying me to compete, or practice, or travel, or take coaching, those were all my choices of how to spend my personal time. Choosing to compete and take coaching, enough to climb the ladder, means you actually lose the ability to work and make income regardless of your job. I still had to ask my boss for time off work just like an amateur competitor woking in an office. I came into work late so I could go to a studio somewhere else and get coaching at 10am. I ate up vacation, personal, and sick days going to competitions. Regardless of where I worked.
For MOST competing pros competition is a personal hobby. Most are not going to make the open final at USDC or any open final for that matter. Most will never see a prize check over $300 if at all. Most will not become rich and famous from it. Most do it just to see if they can do it.
I think one of the big differences here though, is that all the expenses a dance teacher has to compete, from comp costs to coachings, etc. are all tax deductible and part of their expenses as a performing arts professional. not to mention the potential to be a sponsored pro with free dresses, etc. so while a pro doesn't make money competing, they are definitely able to take those costs and use them to their financial benefit.
