I'm totally ignorant in all of that, but for me it just looks like out of sudden (historically) we have way too many males. They used to be killed during hunting, wars, competition with other males. Since 1945 we haven't had that. Men became not as hot commodity. This is the motor of the current social changes, isn't it?
For example: only 40% of all Homo Sapiens Sapiens males that have ever lived were able to have offspring. Compared to 80% females.
