Good, fast, cheap. Schedule, Scope, Cost. Pick two.

These are the buyer's rules of any market; they're known as the Triple Constraint or the iron triangle. In the SMP, good (scope of project, what you want to accomplish or obtain) obviously speaks of the quality of the man being sought in status, personality, wealth, looks, and most importantly, willingness to commit. Fast (schedule, time to completion) is how readily a relationship can be found in terms of time and effort, and cheap (cost) speaks of what qualities the woman must possess to buy said man in terms of physique, personality, social status, and sexual history.

Traditional marriage placed emphasis on scope and schedule. Schedule was imperative, women had to get married because society frowned on spinsterhood. Further, they had an interest in selecting the best provider they could find. Marriage age was relatively low so cost wasn't a big issue, most women in the market were competitive; that is, they were generally young, and more attractive both in physique and personality then they are today. So in a sense cost was basically invariable (at least over the course of the time frame most women spent looking), and scope largely meant what profession of man was being sought, which could potentially be improved by varying schedule (not settling for the first suitor). The relative permanence of marriage influenced cost as well, since men had a reasonable expectation of fidelity.

Hookup culture redefined that to emphasize schedule and cost. More precisely, the sexual revolution threw out scope as a consideration; women simply didn't have to pick a provider, they could provide for themselves. The result was the 80-20 phenomena. They could immediately have relationships with no concern over how well that relationship would serve them in the future. So why cost? Well, because in pursuing anyone they wanted, any notion of fidelity was lost as an afterthought. They threw away a quality they had previously been selling. Technically this was asking men to accept women they previously wouldn't have; and men did, by dramatically slashing the scope of what they were offering down to simply hookups.

But post wall spinsterhood is where that decision comes around. Scope becomes important, meeting someone who can and will provide. But cost must remain on the table, because after hitting the wall, they have very little left to offer.

It's not an exact fit of course, it's just a thought exercise.
