Men will always be "in charge" because male is the dominant sex.
You are confusing the male tendency to take control of things and be dominant with the actual ability to have power and the ability to be in charge and dominant. Also that is not necessarily an advantage to be in that position. In charge can have burdens and lead to restrictions and it all comes from knowledge not from the gender of being a male. Knowledge enables you to get into any position and it would be absurd to suggest males are more knowledgeable than the female gender and basically is saying females are inferior/less capable. Physical strength does not equal dominance it is an aspect of man. Like the female aspects ability to have babies. If you ever tried marshal arts you already understand why strength doesn't always help. In some cultures it was the men considered useless because they couldn't have babies so they were not 'dominant and in charge'. I'm not saying men are useless just pointing out your unbalanced thinking and how it would look from the other side. The truth is each gender needs the other and are equally Dependant. Your use of the word 'dominant' suggest there is some advantage in being male but this is not true each gender while different has equal advantages.
