"Aye,there's the rub..."
Men are more likely to succumb to alcoholism[0]
Men are more likely to succumb to gambling problems[1]
An estimated 84% of homeless are male in the UK[2]
Alcoholism and gambling are some choice indicators of inequality that Tony Judt liked to reference in Ill Fares the Land[3]. The gender disparity is well documented at the top (e.g. Gender diversity for C-level) but this is the 1% of the 1%. I'm not denying that the lack of diversity is alarming but these men are the men that bested many other men. However the fact that there is a lack of diversity on both sides of the spectrum seems to be an inconvenient truth that most prefer to avoid.
