A few years ago I was on a forum that was basically all women talking about dating. A small minority of those women were very interested in how to determine what a man might be earning, and a couple of the posters quite smugly said that they could tell exactly by what he was wearing and what he drove.
I pointed out that if finances were a priority, what they really needed to know was net worth, not salary. And I reminded them that if you're sitting in it, or it's on his wrist, it isn't in his bank account. I thought that they were probably dating guys who believed that you should spend a year's salary on a car, and would be on the bread line in two months if their brokerage firm got bought out.
I knew some very wealthy people who had made their own money, and they didn't flash it. The men had nice watches and usually drove a very nice car, but the thing that stood out to me was their quiet confidence.
