People don't fit into the workplace based upon their physiological capability to grasp the highest role. You need more information than that to determine systemic sexism. People have free will, life circumnstances seperate to corporate goals and a nature. You can track a bias towards food and water that starts from birth and runs through all of society. We don't explain the lack of people in deserts as systemic waterism. Why do we see women working voluntarily with women in some roles as sexism when it has happened since the beginning of time? The systematic worldview breaks down when it hits the nature of people. We aren't all pawns in a corporate game 24:7, so there are many reasons for people to work they way they do. One would hope they are freely choosing their work roles and not living their lives according to the dictats of gender equality statistics.
