This is one of those posts for throwing around ideas. The topic under consideration is "how are women ruined for marriage?". I have been mulling over what happens in a culture when young women are given an abundance of attention and offers from men. Just 60 or so years ago, there was not such a superabundance of opportunity for young women. There was no social media for men to be constantly "liking" women. Sex before marriage was still frowned upon and marriage itself took place much earlier. Women were still more likely to live at home before marriage, making short term live-in relationships less likely.
Most young men won't ever know what it's like for young women today, i.e. to have so many options and to know that if they drop one option a new one won't be far away. I do believe that this helps to ruin women for long-term committed relationships and, for that matter, for deeper forms of committed love. Instead, it sets up women to treat relationships as "play"; to take a more casually dismissive attitude to men and relationships that over time is corrosive of love and of the ability to pair bond; and to orient women more toward serial monogamy, if not casual relationships.
I suspect that men would be similarly affected, if they had the chance. Some men who have mastered "game" and who feel confident in their ability to seduce women on their own terms report that they eventually feel a sense of loss in reaching this stage, as they are no longer able to feel the same love for women that they once did. And when the balance of relationships changes men can also be similarly spoiled for relationships, for instance, in older age groups.
The feminist inspired sexual revolution may have robbed women of one of the deeper experiences of life, namely the capacity to achieve a loving, deeply bonded marriage.
It can seem daunting, though, to envisage a way to reverse the modern trends. Technology like Tinder and even other more sedate online dating sites isn't going to go away. Nor is it easy to control access to popular music and film which encourages a sexually "liberated" culture. The opportunity for young women to enter the workforce and live independently of their families isn't likely to change either.
This can make some people give up and just hope for the best. I do think it's worth trying to be counter-cultural on this issue. Not all young women, even today, are ruined for marriage. The ones who seem to survive best grow up in a loving home and meet their future spouses early, before too much spoiling happens. Parents do still have some control over their daughters before they move out, and in theory churches might still be able to have some influence over the moral outlook of young people.
(I should point out too that it would help if marriage was understood as being based on more than just feelings, but was held to be a sacrament binding two people; and an institution in which individuals were able to fulfil lifelong purposes such as those of being a father, a mother, a husband and wife; and as an institution in which a culture of family life was upheld and transmitted from one generation to the next.)
The culture war is a bit one-sided at the moment, but it needn't forever be so.
P.S. If it's not clear already from the post, I believe that part of the solution has to be ending the "free for all" situation pushed onto Western society by the sexual revolution. It should be replaced with some kind of "intelligent restraint", i.e. a system for the pairing up of young men and women that is intended to foster successful marriage. That is what traditional societies did and I think you can see from the modern Western experiment that traditional arrangements did have a reasonable purpose to them.
