Women can do a lot if they believe on themselves. Is there anything more physically painful than giving a birth to a new one! It is just that we have made women psychologically weak so their physical strength is minimized.
I don't know about other societies but in my society I have observed that some (or many, I am confused) women taking advantage of being this gender go on avoiding the tasks they could do and then more responsibility lies on man.
Being a women brings us several disadvantage in our society. Nonetheless, that's not the whole case, it gives us several privilages too. And sometimes, these privilages are misused. For instance there is stereotyping of domestic violence about men. Women having this in the back of the mind go on for doing emotional abuse to men, and if men ever respond with aggressiveness, he is cursed.
Well there are cases of all kind.
