But, the fact remains, most bankers are pleased with their lot and most menials are not. If they were allowed to trade jobs, more menials would trade than their banker brethren.
Some jobs are classified as entry-level because most people don't want to stay in them for their entire careers. Little girls used to dream of becoming ballerinas or nurses.

I doubt that many little girls dream of a life as a professional floor washer. Hey, I could be wrong. I'll ask my daughter.
