Well the guy doesn't need to prove anything. Majority of people are judgy. But why limit your romantic chances. Why not something meaningless, e.g. Entrepreneur, I deal in classic cars.
Because both suggest a level of financial independence?
I've been on dates that have turned into wealth interviews after the initial breaking the ice chit chat. It's more common than you might think, especially when you get past middle-age.
I'd rather figure out if they're that type of person sooner than later. Easy pass on the second date!
The sooner you internalize this, the wiser you will be. Notice that I didn't say "happy".
i would state it a bit different / from a slightly different ... viewpoint:
"all in life is some kind of selection (!)"
on every level, in every moment ...
cheers, v
