Even if we assume that this CEO gender gap is caused primarily by sexism, what exactly are we even supposed to do about it?
I'm going to guess most the people complaining in this thread want discrimination against men in hiring (hiring a woman less qualified than at least one male applicant just to have more women) if not outright quotas.
I don’t think people here are daft enough to argue for such. More likely is the trend of workplace feminization will just continue. Employers have been weakening incentives for risk, innovation and competition and stifling their employees under HR-gobbledygook for years, which are both feminizing influences.
