In this age of equality, it is fashionable and politically correct to believe that everyone is the same and equally capable.

This is true, but also one side of the story. Everyone is also different and unique in their own way with traits that others don't have.

Men have a natural inclination to think big, aim high, and do great things. They enjoy taking on big responsibilities with fellow men in a peer group. Without their group of like-minded men, they wither away. The basis of this can probably be found in human evolution.
