This is a good example of why people should NEVER assume the socio-economic status of an individual because of their OCCUPATION, APPEARANCE, etc.
Throughout our everyday lives, I'm certain most of us have crossed paths with a wealthy individual, and it would be some of the most unsuspecting people because of the way they choose to live.
This reminds me of the stereotypes I normally face because of my age, appearance, etc. I've yet to become "wealthy," but so few people "know" anything about me as an individual.
I think it's a good rule of thumb not to assume.
