I think this premise was flawed from the start. If women are selective in their mating habits, men will be selective in their behavior patterns. Men in (let's say) the 1940s may have wanted, to some degree, to be wild and irresponsible with the ladies but for the most part couldn't get away with that. The result was that men settled down and behaved responsibly in order to find one good woman.
When feminism convinced women to start giving away milk for free, it had the result of convincing men that responsible behavior had little real benefit. This situation has not worked out well for either men or women.
A move to a more moral society would be a great improvement. I suspect that women may have to lead the way by moderating the degree to which they treat sexual relationships as inherently unserious.

Like it or lump it, the overall morals, objectives, and actions of men are driven by women. Women have the power to raise, or lower, the standards men aspire to. Even in my youth (’60s) a common statement was, “no girl is going to want to go out with you if (Insert: don't have a job; don't have a future; don't dress nicely; aren't clean and polite; etc.)
I had absolutely no desire to wash and vacuum my car, get dressed up on a Saturday night, go to something I didn't really like (a prom), do something I really, really, didn't like (dance), make ‘conversation’ and meet parents.
But you did those things for one reason only - because that was what girls demanded.
The future-less, shame-less, rudder-less guys you see drifting around looking like clowns are that way for one reason, and one reason only - because girls are ‘cool’ with it.
