Your comment's framing makes no sense to me. My wife pushed for me to go into engineering instead of academia so she could stay home and we could be comfortable. We're married. We have kids. The entire point is we're not independent. That's what married literally means. Unioned. Joined. There is no her and me. There is us.
Why would you need or even want to be independent? Why would you plan to form a family while keeping your options open/having one foot out the door?

Because I would want my kids to be able to get out of an abusive partnership if they needed to. See the history of domestic abuse.

Everyone should have options open for basic sustenance. Death, abuse, job b loss, etc. As they say in engineering, two is one and one is none.
Plenty of women (and men) end up in relationships they hate, and if they have no independence they are pretty much fucked. They have no way to escape. Women having options makes a huge difference.
What you are describing is pretty much ideal for a lot of people, but it's not what everybody gets.
