It'd be nice if we could maybe admit that people work differently, without having to stack-rank it.
If women don't like the pressure to be a stay at home parent, then women can start marrying men who make less money than them (men don't as a group place little value on their partner making more than them) and instead face the pressure of providing for their family.
Why don't we set aside the biological differences (all of which we have the means to offset) and tackle the most obvious problems first.
Because short of growing our young in labs, biology is the one thing that cannot be removed from the equation.
The answer is that we have an ideology strongly rooted in the past and justified by the ridiculousness that is modern evo-psych.
You're right that men and women may have different views. The overwhelming majority of women in my parenting group who could afford to were very excited to go back to work. The majority of fathers had a romanticized view of staying at home.
Maybe my experience is an outlier, but I think that after a few months both parents have developed connections with the baby -- it's just that half of them are told by society that if they haven't it's wrong. There's a reason that many women develop postpartum depression, and I don't think that it's entirely chemical. Being a stay at home parent is extremely isolating.
Sure. But there's also centuries of entrenched societal structure that is only slowly dissolving. And much of that structure was built up with bogus explanations of what women were biologically capable of.
So at the very least, we need to carefully consider both biology and possibility when we talk about this. But if we're going to err, I think it's worth leaning the other way for a while. We'll never really know where the true balance lies until we try things with the assumption that biology is not all that important.
That's certainly popular for most topics on Hacker News. Can people live on synthetic food substitutes? Let's put some up on Kickstarter and see! Do humans have a natural lifespan? Let's try pretending otherwise and see where we get. Maybe we could also favor it for radical ideas like women having careers.
I don't think the centuries old explanations are as bogus as you imply. The differences between men and women that we can all agree on such as avg. strength, breast feeding composed a lot more constraint on the divisions of labor. Regardless of what you think about breastfeeding or formula today you can't argue that it more or less forced women to do the early child rearing in centuries past. And men's increased brute strength was far more important for much of the labor before the industrial revolution.
"Natural differences" was also used to justify slavery. That goes back to Aristotle, and up through the US Confederacy. I think that was bogus too.
I also assert that the claim of individual differences can only ever justify individual situations. If a strong person ends up having to carry the coal because a weak one can't, fine. But we're talking about systems where millions of people were judged on hypothetical averages and the crudest of stereotypes. E.g., firefighters need to be strong, but there's no reason to think that the US's weakest fireman was stronger than the US's strongest woman.
And I think that the reason women were forced to do all the childrearing was mainly not biology. Even if we ignore things like cow's milk and wet nurses, dads are perfectly capable of doing all the work once a child is 2 or so. Women were forced to do it because they lived in patriarchal societies where women were nearly property.
So I think we should always be deeply suspicious of any justification that comes down to natural differences. The history of it as an argument is absolutely terrible.
