It's all too easy to say "oh but men are the ones cheating women at least end the marriage" when divorce laws favor the lower earner and 2/3 of husbands outearn their wives.

So while it's acknowledged through the regime of no fault divorce that it's acceptable in society to end a marriage any time for no reason or any reason, men disproportionately face a Sophie's choice of having to pay through the nose for the crime of changing their mind, while women, as disproportionately the lower earners, benefit from changing their mind under the laws of divorce favoring lower earners.

And again, even if the couple agrees beforehand that they will both continue working even after having children, it's not an enforceable agreement. So what should the guy do...divorce his wife right after she's given birth when she says "no actually I'm going to do the mommy track"?

Non lifetime marriage, which is marriage today, is thus a grubby resource extraction scam meant to maximize women's benefit.

Why bother? A man today can have any damn thing he wants without marriage...sex, companionship, adventure, even children. Thanks liberation! (Now time for men to join the ranks of the free)
