discriminatory laws and statutes for musicians

Musicians are and have been subjected to much musical discrimination over the years. In fact, it is still prevalent in 2019. In Myrtle Beach, S.C. county of Horry, discriminatory laws and statutes for musicians still exist.

From: WMBF News, in their investigation they discovered musician Rich Johnson, a musician from Long Island, makes as little as $75-$100 per night playing music part-time at a local restaurant. However, the City of Myrtle Beach in answer to the " musical discrimination" issue, insists under penalty of law that he spend $100 on a “business license” and if not face up to $500 in fines or a month imprisonment for each unlicensed performance. Does this make sense? What other jobs in Myrtle Beach require a license to work? Why are musicians treated like "second class" citizens and made to pay for licenses to work?
