My sister, I distinctly remember a conversation with her that was very classist. She would never data a plumber, or janitor, or anyone with a lowly job. Would she date a guy with a "lowly" job, if he made considerably more than her?
I knew a guy who was a butcher. He owned his own butcher store, and was VERY well off. A small business owner in a skilled-trade field can make a LOT of money.
Hmm...have to restart that conversation with her. Her current boyfriend is an accountant just starting his own company.
