The sadness I feel is that there was, once upon a time, an equilibrium that achieved a pretty good work-life balance for many family units existed and had evolved organically, over thousands of generations, independently in many different societies - it was called the 'traditional family' but it was relentlessly attacked, undermined, and ultimately destroyed by a particular kind of feminist. Whilst there were certainly problems with that status quo, I am not sure that we've improved the lot of most women as a consequence of this change.
Here I can partially agree with you (if we set aside for the moment the legal situation, women as chattels, women unable to enter into contracts etc.)
A society which is set up for families to be supported by 40-odd hours of paid work , e.g. to have one working parent and one SAHP, a 'traditional family', would indeed in many ways be preferable. It would also be far more flexible, as the parents could then arrange for each of them to work 15 or 20 hours if they so desired.
You mis-diagnose the cause of why this is no longer the case in most Western countries - it was not the fault of feminism but of rampant capitalism, exacerbated by energy crises.
In the sixties or early seventies, a blue-collar worker (at least a unionised worker in the USA) could afford to pay for the house, have a full-time SAHP, a couple of children, run a car, and afford a modest two-week holiday each year.
(In the UK they may not have afforded the car, but the landscape is more compact and buses were the norm.)
Now a single childless person cannot afford all this. A childless couple can barely afford this.
