This is how I see it as well. More women are major breadwinners. They are the ones who will be paying more alimony soon. They will want the laws changed and it will happen."He" won't. Because, elite women will be the drivers behind the change, unless the wheels fall off completely before then, which is a real possibility. Look at how big alimony payments to men are covered in the NYT; when men are the recipients, the women attempt the usual shaming tactics, "he's not a real man." That might have worked 20 years ago, but now the guys just laugh. In the next couple of years, most medical, dental, and law students will be women, if they aren't already. So, it's not hard to see how this is going to go, if the trend continues.
Now, you might say that this situation will only apply to elite women and normal women will be hurt when the gimme store gets closed down, but it won't matter. Women will dance in solidarity to whatever tune the female elites call, just as they have done since Seneca Falls in 1848.
Male pride is an obstacle in the divorce game that men will have to learn to ignore. And my feeling is that they increasingly will. Why be a 'man' when it means being left poor?
Many states are going to a strictly 50/50 split. With more women being the breadwinners, I also expect the marriage rates to decline among them, because they won't want to risk their financial security. Women generally don't feel the same responsibility to take care of a man the way that men used to feel about taking care of a woman. It is what it is. Men are supposed to be a man, after all, and that means not taking handouts from anyone...it's unmanly. That's not to say women don't care. Of course they do. But why risk your finances if you don't have to? Prenups galore.
