They do play role , what I was trying to say is that results are not necessary positive, they are opposite to evolutionary . Its clear that women prefer to date rich alpha males, however we see the effects it has on modern society, 80/20 rule didn't exist in medieval and feudal times, because we had caste system women had to chose someone from their caste they couldn't marry up. A more conservative values drive evolution where choices of women are actually limited. Liberal values ace counterproductive and destroying western society. (80/20 rule when 20% of alpha males have relationships with 80% of women) Conservative values are more conducive to evolutionary processes.I think we can say with a good degree of certainty that biological factors have a great deal of influence when it comes to who men and women choose to mate with.
