I don't really see how women would ever be satisfied not gaining the same rights as men quite honestly. The careers that women were traditionally limited to before the sixties, were what? Nurses, secretaries, teachers, and people in care-giving roles? Not bad careers of course, but not every woman is suited for them. There could have been a brilliant scientist out there who never got the chance to make an amazing discovery because the opportunity to be a scientist was unavailable to her. Women's rights in the Western world was going to happen whether you like it or not.
How exactly is marriage suffering though? Because you don't have to stay with someone out of financial security? One could actually make the argument that marriage has a deeper meaning than it once did previously since many traditional marriages were more like arrangements before women got equal pay.
Maybe women's rights didn't ruin marriage. Maybe they saved it?
