The requirements are different, a woman can reproduce as long as she gets food and shelter since finding willing men is easy, a man have way higher requirements on social status before he has a reasonable chance to reproduce. So you'd expect anyone to get violent when they are starving or homeless, but only men to get violent if they don't see themselves getting a sex-partner in their future.
