Its about removing competition. As a rule, men are more ruthless and cut throat. They are ego driven and carry much more anger and hatred. They look for more fights than anybody to prove their toughness. In ancient times they could easily physically dominate women, so that immediately pushed women to a lower level. Control always comes down to war. Whoever wins the war writes the rules. If women could win the war, they would run the world. But they have too much love and caring about others. Men have more of a "me first" attitude. When it comes to being first, or on top, they don't really care about others.
