If you go back and take a good look at history through out the ages, men have always been accountable for financial support. Maybe not to the one-sided degree that we are now, but always.
But in the past, men were also allowed the authority to go along with the financial support. If the woman was his, then it was his responsibility to pay for her.
All that has changed now. They want the men to keep paying, but the woman can do what she wants.
No fault divorce is a great evil. A man can get married and do everything right and through the whim of his wife she can break her promise, take his house, and his kids, and then the still expect the man to pay for it. And if he refuses he goes to jail. This is a very new development.
Read some 19th century literature. In the 1800s a divorce took an act of parliment. And if a woman wanted out she could not take the kids with her.
Later, in the 20th century, she had to prove wrong doing in divorce to get anything/everything.
Anyway the point I am trying to make is not that financial support is anything new. What is new is that it is stripped of any kind of authority or accountability from the man. He is just a cog in the machine who has to turn over the majority of his paycheck even though, through no fault of his own everything important to him has been stripped away.
I would say MGTOW is a direct and logical response to no fault divorce specifically, because civil marriage, at least in the U.S. is a really bad deal for men. Further, as Dalrock has demonstrated, this model is not sustainable in the long run. The system is going to collapse.
