"What seems to have worked best for cultures is to play off the men against each other, competing for respect and other rewards that end up distributed very unequally. Men have to prove themselves by producing things the society values. They have to prevail over rivals and enemies in cultural competitions, which is probably why they aren’t as lovable as women.The essence of how culture uses men depends on a basic social insecurity. This insecurity is in fact social, existential, and biological. Built into the male role is the danger of not being good enough to be accepted and respected and even the danger of not being able to do well enough to create offspring. The basic social insecurity of manhood is stressful for the men, and it is hardly surprising that so many men crack up or do evil or heroic things or die younger than women. But that insecurity is useful and productive for the culture, the system."
