Yeah, I think its only been a win for a short time. Maybe, for most of history hierarchy within the genders has mattered a lot more for sexual selection. And your position in the hierarchy is usually determined by your success at gender specific roles. So if you want to be the the alpha male you need to be really good at hunting and so the best hunters win. Similarly, power in the female hierarchy was dictated by things like child rearing and social knowledge. So those that focused on that won.
