Do men have an inherent advantage in terms of equality?

No. Globally, males are born with ascribed status. As well, males have not always been at the top of the heap. How do you know that in the days of the caveman and primitive societies males were in command. No matter if you perceive laws as artificial. Taboos are the same as morals. Can you visualize the anarchy that would exist if there were social controls in effect.
