Earlier quoted context omitted.
Women can't all "marry up" unless you systematically disadvantage all women, such that for F1, there is a M1 who is of higher whatever (status, income, looks), and so on for F2 and M2, F3 and M3, and so on. Given the stats on enrollment in colleges, on who is preferred for tenure track in academia, and so on and so forth, well ... that's just not gonna work out.
This is not a binary decision, there is a third choice of not marrying at all.
Of course, nobody cares about men in and of themselves, so that's not really a problem.
