I have to disagree. Men haven't lost any rights. Men are just simply facing greater competition that they didn't face years ago. They were once able to go to school and get jobs easily because fewer women were going to school and work, and therefore, there were more spaces to fill for men at school and work.
They just simply need to learn that they will have to work hard for what they desire. In other words, men need to realize that they're not going to go to school, get good grades and get a job just because they're men. They are going to go to school because they desire to get education. They are going to get good grades because they made the effort to study and do their work. They are going to get a job because they have the skills and character that meets the employers' requirements.
Men also need to learn to take on equal roles in parenting that once did not exist. I understand that some workplaces do not offer good leave of absence to care for children, but men still have the power to ask their employers to offer better benefits.
We can't ignore the fact that there is still a substantial number of women in developing countries facing severe equal rights issues that includes being kidnapped and taken to brothels, having lack of access to clean bathrooms and education, and receiving lower quality of medical care than men.
