Imo, there are a couple of problems with this approach. Problem number one is that not every man is an "appreciating asset", whatever pretty lies they may choose to tell to themselves. I constantly hear how women have "an expiration date" (apparently we all become infertile somewhere about 25-26) and that women "age like milk" while men "age like wine". The truth is that many older men are hardly a catch themselves. A middle aged overweight alcoholic without a stable income isn't going to attract "a young nubile virgin" however hard he tries.
Women are often accused of only running after highly desirable men and not wishing to settle, but vice versa can be also true. There are lots of men with unrealistic dating standards. They will gather on the internet and spend hours
If we look at the marriage purely from the "market" point of view, then we see that the higher quality women will look for the best of men, and high quality men do the same. Like attracts like. Take tattoos, for instance. Let's be honest, tattoos are a class marker. Outside of hipster bohemian circles, as a rule "a lady" won't have one. But, not every man is a gentleman, either, and not every gentleman wishes to marry a lady. So a nice middle-class church going guy may be repulsed by them, but some biker or an alternative type will hardly ever care.
Considering older women there are lots of older single/divorced/widowed men, probably with kids of their own who don't want any more children but would like to have a stable home and a partner in life etc etc. There is a "market niche" for everyone. So, to sum it up, my point here is that "losers" come in both sexes, and there is always someone for everyone, if only both men and women can get rid of unrealistic expectations.
And here comes my second point: should we as Christians reduce all the interpersonal relationships purely to the market exchange? Is that what the right-wing thought has finally come to? That we view our fellow men and women as consumer goods? It also doesn't work, because human beings aren't computers and aren't motivated only by the ideas of profit (and for those who are, please, seek help). We also have emotions and feelings, and though we shouldn't be ruled by them, they aren't to be completely disregarded, either.
As Christians, we ought to believe in redemption. Yes, both "sluts" and "bums" can be redeemed, can change their ways, clean their life and find happiness in marriage. Marriage isn't only for the upper class, it's for everyone, yeah, even for those who made mistakes. "Merchant right", those who reduce everything to the economics and "market value" can be conservative, but traditionalists, they aren't.
P.S. I don't mean that people shouldn't have standards as to whom date and marry. For instance, if we take divorced people, some churches, like the Catholics don't technically allow divorce and it could be against convictions for many Christians to marry a divorced person. If someone considers marriage, it's not wrong to exclude certain groups of people as potential marriage partners. However, these standards should be realistic and when dealing with people, even online it's always good to be more charitable, so to say.
