You mean to ask which career suits men better in today's world (the current jobs offered for both genders?)

it roots from the idea of patriarchal society where fathers have primary responsibility for the welfare of, and authority over, their families. The concept of patriarchy is often used by extension to refer to the expectation that men take primary responsibility for the welfare of the community as a whole. It also goes with the superiority complex and ego of man. but today, i believe there's always space for male and female equality.

Yes, they should. And women should, too. (Your question would sound better if it started with "Should..." - "Should men have (/do) a relatively better career (than women)?"
