Re: Self selection and poor selection for better paid roles
IT isn't "sexist". It's a brutal meritocracy. This is especially true for places like Silicon Valley. A lot of guys can't cut it and do little more than occupy space. They would quickly get ejected from a high demand IT environment.
Women self select against IT for painfully obvious reasons that have nothing to do with this "sexism" narrative. HELL, this sexism narrative is one of the things keeping them away. It takes what little supply there might be and reduces it even further.
The smart ones gravitate towards jobs with better pay and more respect. They gravitate towards professions that are glamorized by our culture rather than shat upon by it. This should not be a shocking result.
