Do they control for economy? Is the definition of “fill time musician” the same? I imagine full time musicians would be impacted by a faltering economy at least somewhat more than most careers and probably one of the last careers to bounce back. Not doubting you as everything I mentioned was based on second hand information with no science other than “as a person in the industry, X seems to be true.” As I said, I would love to see a world where even mediocre artists can make a livable wage.
