That's a fair point. However, alimony can most certainly extend beyond the age of majority for the kids, and marital property is usually divided in such a way as to compensate a woman for taking time off to raise kids. Social Security also allows divorced women to partially receive benefits based on their ex-husband's income, even income earned after the end of the marriage.
Regarding my lack of faith in the HN community, I like your attitude, and I also take downvoting seriously. Unfortunately empirically the comment was downvoted, so obviously not everyone agrees with us. It's become politically (both here and elsewhere) unacceptable to have a belief that perhaps being a woman in America isn't so bad. I think it's worthwhile to have this discussion, but I'm not interested in having my head put on a pike for it.
