This is an interesting conversation to say the least

I think few people if any think that men and women should not take equal part in life’s labor, I just think it’s the labor that has changed

I do think there is a gendered predisposition for women toward aesthetics and socialization, and likewise for men for physical toil and risk-taking. But if aesthetics and socialization can be bought with money, and physical toil can be avoided and risk managed with money, and the western world’s methods for procuring money are not gender specific, then the need for traditional gender roles certainly diminishes. Essentially, with enough money you can replace a wife or a husband. 

The question then is two-fold - 1) is it ok to abandon traditional roles because we are sure we’ll never need them again (should we maintain them as a backup?), and 2) are we sure that our evolutionarily rooted needs are not being abandoned if we abandon these gender roles (Chesterton’s fence)
