Since you added the note, I'm inclined to agree with you to some extent. The traditional role model is certainly still attractive for many, both males and females, and if they want to live it, good for them.
However, I'd argue that way too often, employers and laws don't take those into account enough who want to live a different model, IMO. Sure, it's biological reality that only women can bear and give birth to a child, but that doesn't mean women who want to have both carreer and family should be disadvantaged towards men who want to have both.
Probably you'll disagree, but IMO, that's one of the cases when regulation and correction of shortcomings of the free market is legitimate, because humans are worth more than what they can make on the market. Call me a statist, if you like.
