Women who have to choose between giving their all to their career and having children because unlike Sandberg they don't have nannies or a 50/50 relationship where they can expect their husband to co-parent.
How is this a gendered issue at all?
Men are also forced to choose between non-career activities and giving their all to their career. Men who choose non-career activities rarely become COO of a $50B company.
Women who aren't mentored by the best of the best and don't have parents who are PhD (dropouts) and Ophthalmologists.
The number of women who have parents who are PhD (dropouts) and Ophthalmologists is equal (within some statistical margin of error) to the number of men who have similarly situated parents.
How is it not a gendered issue? Women are generally expected to be the primary childcare providers, and if you can't afford a nanny, the wife is going to be the one who does most of the childcare.
Any woman who chooses to spend the majority of her waking hours engaging in non-work activities did so knowing full well it will probably harm her career.
If she didn't want to do this, she could have freely chosen to a) not have children or b) have children with an unambitious man willing to become a full time parent.
If you want to argue that women are somehow "defective" because they prefer children to careers, be my guest. But it is dishonest to call it a glass ceiling - that phrase usually implies it's something inflicted on her by other people.
She could also have children with a man whose ambition is to raise children. (Don't make the mistake of thinking stay-at-home parents lack ambition! It's just directed at kids rather than money, power, or fame.)
