I don't think that talking about the truth is sexist, particularly when it's naming the patriarchal beliefs of many men that are still well in evidence today. I'm sorry, but that's a kind of lame deflection. The fact of the matter is, more and more women are unlikely to marry because they see what happens to women who do. No-one needs to sell them on it or browbeat them into it - the handwriting is on the wall. It's over all a bad deal and women who have done it once are a lot less likely to ever want to do it again. We've been talking to men about this for 50 years already. If many of them persistently refuse to listen, well, it's going to be an interesting culture, because a lot of women have had just about enough, and they no longer need men for financial security or for social status.
Most of them still want male companionship, but they want it on their terms. Even my rather conventional mother refused to marry or live with her partner of 22 years that she had after my father died. She didn't want to have to cook for him or do his laundry, and she wanted the independence to do other things that she wanted to without having to run it by him for approval.
Based on that, among other things, I find it hard to believe that this is a new phenomenon. You said that both your wives did not work outside the home, and so in that instance it would make more sense for them to do the bulk of child-rearing and home-keeping. But most couples nowadays both work outside the home, and women still do the vast majority of all child, elder, and home care - even when they make more money than their men. Mowing the lawn once a week and taking out the trash simply doesn't equate to the constant unrelenting onslaught of laundry and dishes, meal prep, and other things that need to be done daily, if not multiple times per day and as soon as they are completed, must be started again. Study after study shows that American men are not doing their fair share of those kinds of things. You should be offended about that, but not for the reasons that you seem to be.
