Distortion 1) You can't take the outliers of a flatter distribution and generalize that to the entire population. You can't even compare the averages of two separate distributions without qualifiers.
It is true, most of the people who run governments are men. Most of the people who own companies are men. Most of the people who dominate C levels are men. Most highly paid professionals are mostly held by men. Most of the top outliers of capital ownership are men.
But it is also true most men don't run governments. Most men are not even remotely close to running companies. Most men are not C level execs. Most men don't have high paying jobs. Most men don't have any capital (if not negative).
Distortion 2) Even if it was true that it was exclusively powerful men's fault that boys are failing, it is completely irrelevant to bring it up when talking about men as victims, unless one would also suggest that boys somehow deserve to suffer educational disadvantages because of those men have a lot of capital, or there is some hidden variable that connects the two events.
