Wait—when you say “men can make more money more easily than women can”, are you saying the feminists are right about the alleged “pay gap”, or something?The other reason is financial. So lose your job, maybe get on disability due to "stress" or PTSD, spend money foolishly, hire expensive lawyers, spend money on the new girlfriend. etc. When a woman's motivation is financial - if she sees the financial windfall evaporating she will want to either back out, or settle the divorce ASAP to preserve at least some of the financial windfall she was hoping for. Don't worry about losing money - men can make more money more easily than women can.
But seriously—impoverishing yourself in reality (as opposed to maybe faking it a little) is a terrible strategy. It may not always be possible to make infinitely more money later on, for living expenses and to replenish and expand retirement savings. (Much less enough money to attract a homemaking-oriented woman and raise kids—assuming you will ever want those things.)
Depending on how the economy goes and to what extent SHTF in the decades ahead, “I can always make a good living again” just isn’t a wise assumption. Even if you think you’re betting on the “right” occupation or trade, investments, etc. (STEM? HVAC? Real estate? Gold? Bitcoin?) For all we know, today’s incipient boom fields are tomorrow’s busts. Remember what happened to our dads’ or granddads’ livelihoods when “the industry changed” and layoffs ensued, or the big box stores killed small business, or whatever?
