I Gots A Headful Of Monkeys

Men built the patriarchy.

We decided it was in our interests to have a society where our - as in, heterosexual men's - values (attractive female mates, who are loyal to us and raise our children) WERE the social values, enshrined within that. We didn't concern ourselves with what women could achieve, we concerned ourselves with what women could be to us. We built our society to benefit us.

Now, a psychologist could explain, easily enough, how this came from an insecure place. A sociologist could explain the details of the blueprint. A historian could explain how many years it developed over.

But all anyone needs to see the patriarchy is a pair of eyes.
