Why would you assume the converse? Hedgefund managers and more junior employees deal with ie sell to the rich, be they extremely wealthy or others in the finance industry. Do you think that's going to work better as Dennis Rodman or James Van Der Something with the accent and style to match? Dennis got a game to rack up his astounding numbers because he's very tall. He wouldn't get a game as fund manager as 25 year old no matter how smart he was.
I'm a CFA, I have grades, never got a look in for fund manager jobs. Pivoted to computing at the age of 30 where I "look the part" or whatever.
Don't kid yourself about this stuff. I'm not from an underprivileged background by any stretch of the imagination and nor do I have any time for socialism and socialist posing.
Young Dennis will get a game somewhere and put up compelling numbers and will likely get to the NBA. The equivalent can't be said for young potential fund managers who won't get a chance to impress. Positive discrimination is not the answer to this, but neither is the ostrich strategy.
