This is a problem deeply routed in society. Men are seen as the strong hunters and protectors that have to take care of their family in physical ways and women are seen as the subordinates that stay home and take care of the kids and their men after a hard day. It's really hard breaking out of that way of thinking when kids and teenagers grow up being bombarded with that role model their entire life.

The perfect example for that would be how superheroes are being portrayed based on their gender and barbie dolls in particular are a bad offender of subconsciously changing girls and young women into that role model of always looking perfect and aiming for that marriage as their life goal.

Edit: Someone commented on this, telling me how Black Widow, among others, don't fit that stigma. Since he deleted his comment before I could respond, the answer to that is simple. Black Widow isn't directly portrayed as a 'typical' woman, but think about the way she acts. Does she show brute force and kicks asses everywhere she goes, or does she use cunning and her looks to make men dance around like puppets?

She may not fit the role model at the first glance, but on a deeper, more abstract level, she works as well as any at subconsciously influencing teenagers into roles based on their gender.
