Times are changing. Society is not the same as it was twenty years ago, this generation of women are business oriented and want to earn their own money. I believe the result is different in each cultures and society. The ratio of men and women in business cannot be the same, corporations value male employees above females because they believe the men will be more committed and willing to sacrifice more hours as they have less commitment to family unlike the women.
As you stated time is changing, but I disagree that corporations value male employees above female employees, what happened to gender equality in the workplace? As far as I observed, there are more females who are easily promoted than males. I believe in employment it is not the gender that is not being looked at but the performance.
About job commitment, your statement can easily create an argument. I believe this depends on the work ethic of a person. Men and women can be equally committed if their priority is their job responsibility.
