We’re halfway there already.
Women can pull the rug out from under the guy with no notice.
He has to continue supplying cash, though.
Now consider if the tables were turned.
A guy could divorce a woman against her wishes and without notice.
She would have to continue providing sex whenever he wanted it or face the loss of professional licensure, or even imprisonment.
Would any woman ever consider getting married anymore under those conditions?
Women are better off being poor but independent. The man stuff needed keeps them poor because they don’t want to be beholden. Can’t blame them.
