Children today have to be glad if daddy sticks with the family. One third of kids in the US do not live with the biological dad in 2017 (I am guessing over a lifetime the number increases). 42 percent of children in the USA are born to single mother families. 

Perhaps men have figured that they were being oppressed by marriage, and have decided to get out. If a woman thinks she has it rough because her husband/partner is not contributing to housework or childcare, perhaps she should look at her single mother friends. The children of single mothers are more likely to be school dropouts, criminals, etc.

Finally, 70 percent of divorces are filed by women. In case of college educated couples, 90 percent of divorces are filed by women. It is upto women to decide what they really want. Men seem to be a lot more accepting in a relationship.
