By too late I mean early thirties. You stated that "after 35 we know women's fertility starts to decline a bit." Actually, by 30 a woman's fertility starts to decline dramatically. The caveat here is the time of first conception. Women who started having children young are, on the main, more fertile throughout their lifetimes (meaning that they ovulate more regularly, have more regular periods, produce more viable eggs, and remain fertile through their 40's, etc.). Women who wait until after 30 to conceive for the first time have many more problems than women who had their first child in their early to mid-20's.
You may ask why I am harping on this. It is simply that by the time that these professional women begin to want hearth and home (because they have spent the first 10 years on their career), it is too late to find husbands and start the families. These women think of themselves as being catches but in reality they are damaged goods. They have usually had one or more abortions, they have political and ideological beliefs that are inimicable to a happy home-life, and they are "past the expiration date," age-wise.
