lol at this, first, globally (all age groups) there are more females than males. Check wiki, the ratio at birth varies within countries, and some policies like killing females, make much more males than females at birth, and China for instance will affect the global statistics of course.
In your countries the ratio will be pretty close to 1. And even if it was 105 to 100, in your current age group, are you telling me you are one of the 5 lower guys?
Girls #1-10 will chase guy #1. The remaining 9 men will remain celibate, alone, and none of their genes will be passed on.
Evolution doesn´t work that way, if that was the case every guy in the world would be super alpha. Being beta, and working in teams it works as good or better than being a lonely alpha, there are multiple personality traits that can spread your genes, hence the large diversity of personalities.
