Yeah, I am aware and almost all of those areas have few high paying jobs where a "sports business" degree is even remotely more sought after than a business or finance or marketing degree. Most of those niches are about getting in shit jobs (not just your usual low level entry) and working your way up, unless you know someone.
If that is what you want to do with your life, why do they have to be high paying.
Research scientists don't get high paying jobs, but the world still needs scientists. You don't have to go to school for 12 years in sports business either.
