Most people look down on butchers (and most other blue collar workers), while idolizing entertainers (and other people who make a lot of money).
"a single entertainer can entertain millions, whereas a single butcher cannot feed nearly as many"
Even per capita, butchers and other blue collar workers are going to be making far less than even a mediocre entertainer. When was the last time you saw an individual pay $30 to $200 (and up) for a butcher to ply his trade?
