Its always been a mans world from the beginning, right or wrong thats how it is. I doubt it will ever change much, just like there will always be racism. I would guess this started when humans were hunter/gatherers. The men did the hunting and the gathering as thats what their physical make fit. And to this day, the ultimate responsibility to support a family falls on the man. Its expected, we're expected to make more money, but you want to be equal, thats a female no win scenario. I dont know to many women that would be happy being the bread winner while the man sits at home, drinks beer, does the laundry, and see's how far he can fling the kid with the home made catapult in his spare time

If you're a single mom with a dead beat dad, they understand that pressure to provide for your children. While in todays world both male & female need to work, the pressure and responsibility is on the man. he can usually make more money and is more dependable and steadily employed, this just doesnt fall on the woman. If one of you is going to not work, its almost always going to be the female. This I know sort of supports your argument, but if you get equal pay or higher even, that responsibility when shift to the female if she is equal or better than her man. And that defeats most womens concept of the mans role as a husband and a father of the family.
If you disagree with that and can make more money than me, I'll marry sight unseen, thats a fucking meal ticket right there
