We are talking about the world not the US, Canada, UK and other western countries. There are parts of the world where women can't vote, drive, restrictions on how they dress, whether they can be seen in public with a man they are not related too, etc. So as a whole it easier being a man than a woman in today's world.
I see the question has been edited to restrict it to the western world.I don't like to delete posts or edit them without letting the reader know.
Now it's a much harder question, but men on the whole have it a little easier than women. Men don't get pregnant, and while it's sad to say there are many business that don't like to hire women of child bearing years, because of just that, but across all professions, women’s careers take a nose dive the moment they reproduce. Women on the average miss more work than men because of childcare, which is generally handled by women. Add to that the health checks, vaccinations, nursery registrations, interviewing nannies or childminders, which is generally left up to the woman. While women do have advantages in certain jobs, they are still held back in others. In some cases it a strength issue, some cases it because they can't easily travel in parts of the world where women are heavily restricted. They also can't serve in combat, etc. And while they do have advantages that men don't have, especially on the social networks, (in my experience women are much better at networking with other people than men) when you look at it in total men still have an edge over women. Part of that is the way we look at women, after all "they can fall back on their man" is an attitude that a lot of people still have. Also if someone career has to give way it's generally the women career that suffers. So all in all men have it a little easier in my opinion.
