Compared to women? Because there are many downsides to being a man that are also downsides to being a woman (mortality for one). I've never been female so I have no point of reference. It seems like men have it easier: being on average stronger and lower voiced (people tend to listen more to lower voices in conversation) and not having periods... but... We can't have children on our own (the species would die out without females but not without males), we have to compete more for mates (average women seem to all want ideal men whereas average men are extremely happy to find an average female that will settle for them... I would say pretty much any female could find a mate, but not so for males), and we're often (this is becoming less now) expected to be the breadwinning, strong, protector of the family, and the one that's expected to die for the other in a life-or-death situation (just think about the Titanic movie).
