I said it's a structural issue, not difference. The issue is that woman in finance face some unique challenges that men don't face. Simple example - when a young woman starts as a trader, it's harder to develop a close relationship with her mentor without sending, erm, wrong signals. For the said senior trader, it could be hard to explain to his wife that he's grabbing a drink with his junior if said junior is a 21-year-old blond etc. For the said junior, it could be hard to suggest grabbing a drink cause it could be misinterpreted.I have no idea what you are getting at. Where is structural difference between men & women?
