No need to single out women in this context. If you want to be a father that's there for your children, both on the infant stage and later stages of their lives...being in a top-level leadership position is simply not possible. Ditto for most other career paths that require your undivided attention.

Cultural norms is the only reason we single out women in this context. A lot of people don't appreciate the level of dysfunction that can occur in other areas of life simply from being ambitious and hard-working. I personally know many professionals that I greatly admire and respect (while acknowledging that I would never make the sacrifices they do to be where they are), but I'm sure as hell glad I'm not married to them.
