Why men make more money than women?
What do you think about this hypothesis? do you have one as well?
And yes what you are talking about with the man having power over women is very true. I must say though that we do compete against other males as well as females. We however ostracized females, putting them at a disadvantageous state for when they finally gained equality. Because of this we evolved men to become stronger physically and mentally. This is why some blacks are so good at sports because (based off my hypothesis) they were still using brute force to catch their prey instead of creating devices like their other human counterparts. ((Not saying they're primitive in fact quite the opposite, in the rest of the world humans were creating devices to fight for more trivial things like wealth and power over other humans.))
