How is it determined if one is white collar or blue collar?
If it’s by the amount of money one makes, then an airline pilot would be white collar but a bus driver would be blue collar. But in a broad sense, they do the same thing.
If it’s determined by the amount of education typically required for a job, then a self made multimillionaire who runs several corporations could be white collar or blue collar.
If it’s determined by whether or not one gets dirty on the job, then a surgeon is blue collar, but a data entry clerk is white collar.
What are the rules for this?
