Group discussion: Gender Issue

We talked about the question number 2 which is "Do you think that men and women are treated fairly (equally) in your country?"
We had 2 Japanese students, one British student and me.
Two Japanese students said that it seems equally in Japan. They think that men are high respectable in term of work, on the contary , women are high in term of family. They consider it as role division which is perfectly balancing.
In England, gender equality depends on case by case. Some case men are higher and some case women are. Toby think it is fair.
In my point of view, it is quite fair in Thailand in the way that they are treated and the way they treat. Thai men and women are equal. Women can be top managers, if they are qualified enough. It doesn't matter whether which gender they are.
Apart from this, we talked about miscellaneous thing for example, general manner. Toby asked Japanese about if woman and man were sitting near the door, when the class end, who will be the first person to walk out of the classroom.
In British's case, men will let the girl go first and keep the door open for them. But in case of Japanese, men will go first without caring about women.
Toby said sometime it was not equal that men have to be gentlemen and let lady first.
However, we can not tell that it is absolutely fair between men and women in each country. Because it depends on many factor like situation, people and their position.
If we judge from the video that we watched last week, we will see double standard between women and men in many ways. For instance, buying secondhand car, finding a job and making an appointment. Men seems to be privilege in almost every case. My question why men have been valued higher than women even though they are in same age, same qualification and same economical status? What is the attitude toward men and women?
