Although the traits formerly selected for, like hard-working and reliable, are still desirable for some women, I think you are correct in perceiving that different traits are being rewarded at the current time. Younger women in particular are attracted by detailed personal grooming (the "metrosexual" phenomenon), an ability to perform in some medium (music, acting, fire-spinning, etc.) as well as being attracted by money and earning power (as exhibited by the car a man drives, the watch he wears, and the electronic gadgets he carries, as well as his generosity toward the female in question in terms of expensive dates and gifts.) Most of all, though, they are attracted by AMBITION--a man who knows what he wants out of life and has a plan to get it. Once in a relationship, women today reward men who are emotionally sensitive, attentive, good listeners, who will do their own share of the housework and childcare.
You imply, and I agree, that these qualities are not ones frequently exhibited by the stereotypical AS man--the kind who have poor personal hygeine, are shy and retiring in public, don't aspire to anything beyond living in their parent's basement, who lives on a disability check from the government. If such stereotypical Aspies do manage to get a girlfriend, they are too emotionally distant and don't clean up after themselves, resulting in dissatisfaction with the relationship.
The 1950s style relationship was better for some AS men, since they weren't expected to do anything much beyond the work/eat/sleep routine, with the wife taking care of all the housework and childcare and not expecting much emotional input from the husband. The "strong, silent type" was actually desirable.
