Social roles by gender

I think that gender roles are continue changed in all the world, basically for the power of the globalization and the opportunity that the women has reach, consequence of many factors like the entrance of this group to the university in the 20 century, the entry of the women into the electoral system, and the progressive participation in the workforce, accessing more to more in better jobs.
Today it is normal to see fathers take care of his children and changing nappies to the babies. The woman can work a half day, and the other half of the day take care to the babies.
The barriers of entrance are the same for both genders (at least by law). When you present the curriculum to the employer, he can´t know your face (photo in the curriculum), and in some companies your gender.
Then, when you are inside the company or organization the things can change in the sense that the "machismo" still rules in some places and men generally reach better jobs and salaries than woman.
I think that woman makes the majority of the effort inside the house, raising the children, cleaning the house and organizated all. In my society it is normal than man brings the "bread" to the house, but this situation doesn´t mean that the couple can´t change roles or the way. I prefer a house without gender roles, this means that both make the same without prejudices.
I think that woman has a life more difficult than man because for instinct the woman assumes a dual role in the society, for one way she wants to be successful in the jobs and for other way she want to be mothers and fledge his children’s.
Finally it is difficult for me imagine that equality of genders can be possible meanwhile the societies uses the force and the violence (legitimates or not) to answer the problems and differences between people.
