For anyone interested, Massachusetts' Division of Professional Licensure can be your entry into the exciting career field of Elevator Operator. You must pay a processing fee of $25, allow access to your driver's license, provide a description of your "work experience in elevators," and (I am not making this up) pass an exam, which I assume goes beyond knowing what maybe six buttons do.

Presumably, the licensing process protects consumers (who, obviously, can make mistakes); aside from ensuring high quality elevation services, why else might existing elevator operators find it in their interest to protect the licensing system? What side effects might the fees introduce into the elevator-operator market?
