I think a great many women and a great many economists (and women who are economists for that matter) would take issue with the notion that raising a child is the alternative to being productive.

Ask any policy maker in South Korea how they feel about the social value in raising children. It's not a film adaptation of a book starring Clive Owen and Julianne Moore, it's 2055 or thereabouts in the China, the US isn't so far behind.

I was not in any way intending to imply I thought that, I was using the language above about economic value. I've edited my post to avoid the misunderstanding, I think you and I are aligned.

I don’t disagree, but there is a vast difference between a wanted and an unwanted child. This is well studied and well understood. See freakonomics episode 394.
