If Only 20% Of Men are Attractive, then aren't 80% of Females the equivalent of Beta?

If only 20% of Men are attractive, then aren't 80% of women beta? Mathematically, there isn't a man for every woman. Men give commitment, women give sex. 80% of women cannot get equipment and are forced to settle for beta, and only the top 20% of girls can get the top 20% of guys, the HB9s and HB10s.

This is assuming women want commitment, I think they prefer fucking as many alphas and riding the CC hard, so maybe a beta female aint as a bad as a beta male. What does a woman in her 20s gain from male commitment anyway?
