Unfortunately, that's not how this works. If it were, then the article wouldn't be citing early 30s as the age at which educated women have kids.
How this works is that a poor woman from a bad neighborhood in her teens is happy if the guy doesn't beat her, isn't a substance abuser and has a job at all. Then she gets an education and her expectations change. Of course, he won't be a substance abuse. Of course, he won't beat her. He also should have a professional job, dress well, and have certain other appealing traits. Her expectations go way, way up.
In most cases, she also is unwilling to give up her career. She didn't get a degree to become a homemaker. Two career couples face significant challenges in finding a city where both careers can thrive.
Things get vastly more complicated and it takes time to find the right guy, among other things. Some of these women start trying to arrange for a child in their twenties and don't get one until their late thirties or even their forties.
Julie Numar was quoted as saying she sometimes wished she was brave enough to have an accident. She married a Texas businessman and had her only child in her forties. She was soon divorced and raised the child alone.
There are good things about getting an education and career as a woman. But for most women, it complicates the hell out of the desire to have kids. Those complications can mean it gets put off and put off and put off.
But I think I'm going to walk away from this discussion for now. It's an overwhelmingly male forum. The issues involved in waiting to have kids that so many women find agonizing are being trivialized. I'm being attacked and dismissed. The basis for my knowledge is being attacked as irrelevant. Etc.
Y'all have fun as men hashing out how women ought to view this issue.
