I of course agree with you advice, but I will add that money isn't the issue in the vast majority of cases I've seen. It is usually a simple matter of priorities.
You are right, of course. Money wasn't the only reason for women going into the workforce bigtime. Perhaps the rising rate of divorce caused that, for women needed to find work to support their children, and attempt to maintain their standard of living. And then feminism raised its ornery head, and gave women reason to feel wasted as stay at home moms - they needed to realize their "full potential". But in large part, money, credit cards, spiraling taxes and inflation, government getting into the medical business (there actually was a time when medical care was affordable by everyone!) made it necessary for women to contribute financially to the "nuclear family" in the very early days. Instant gratification became the norm. Priorities changed for whatever reason, and the children paid. And the children (the future)are still paying. Thus the entire country is now paying to its detriment.
