As a general guide, within any socioeconomic stratum, the premium women were swept up by the prescient dudes - circa age 18, the prescient blue collar dudes grabbed the best blue collar women they met in high school; circa age 22, the prescient white collar dudes nabbed the best white collar women they met during undergrad, circa age 26, the prescient geniuses grabbed the best genius women they met in grad school, etc etc etc. But there comes a point where, if a woman hasn't been snapped up by a dude, then there's probably somethingthey fear there is at least moderately wrong with her psychologically, which is very unfair.
