For context: this thread was started by a guy who not only went on record saying he didn’t „know why people who pursue FIRE get even married at all“ and that people „can be together without mariage“ just two years ago - but also (temporarily) separated from his girlfriend (though not split) only a year prior.
Now consider his phrasing in the original post („ marriage is around the corner (…), it made me think more about a marriage contract“), his sense of professional achievement and financial entitlement (literally, without judging on my part: „am I not entitled to a higher net worth even in marriage?)“ and @Cortana’s devotion and time spent on this „Mustachian thing“ (200 hours and 45‘000 posts read on this forum alone).
I can‘t help but conclude that by marrying this girl without a marriage contract he would do something that goes against his personal values and beliefs. And worse, if the marriage indeed goes haywire, let alone has children involved, his gut feeling and his rational thinking - both of which told him to get a marriage contract today - will come back haunting him. Painfully. He’ll know that he knew about his mistake all along, from the very beginning.
Not only is the financial risk to him substantial.
His mental potential of regret will be even bigger.
