Women live in a man's world. Men create the environment under which we all live. The world is managed by the male of the species.
The subjugation of the female is most apparent in certain countries and cultures but is worldwide. The Muslim faith comes to mind with a prejudice against women that is sometimes distasteful. I am thinking of so called "honour killings" - highly sexist and prejudicial male behavior.
It must be inherently difficult on occasions and even intolerable on other occasions for women to live in the male world. Common sense suggests that this must predispose some women to stress and depression (better described as unhappiness or a lack of contentment - "depression" is an overused word).
It is, after all, pretty difficult for most men as well because the world is managed by the alpha type male of the species of which there are relatively few. Alpha males tend to use all other people to their benefit.
