It looks like taxes increase and any kind of post-life planning can be done with a few legal filings rather than getting married. Is there any real benefit? It kinda seems like it’s just a way to trap people in relationships, probably traditionally, the woman.
American marriage tax codes are written to benefit the sort of couple with a stay-at-home-spouse. Having one person without an income (or with a significantly lower income) in the marriage effectively pulls you down in the tax brackets as a whole.
