But that hasn't happened yet.
I agree the true equality hasn't been achieved, and I do not believe ever will be.
Beyond the point that happiness is a ridiculously vague thing to try to measure, let alone try to calibrate a scale that is consistent over time, I'm not even sure that happiness even means the same thing in different time periods.
Perhaps, but then can one say anything at all about whether one system is better than another for its people? Feminism makes all sorts of claims about how terribly bad life was like in the past, but whether it has made women happier is a terribly vague question an what even is happiness?
This is the same pivot homeopathy does when it talks about how clear and obvious it's ability to cure people is until you come to test it, and all of a sudden it is so subtle that there is no way to tell if it has done any good. This makes feminism unfalsifiable.
Expectations.
When I grew up, there were no cell phones and, until I was around 10, cable television wasn't a thing. We didn't miss either one. We were perfectly happy without either one and felt nothing was missing.
Now we have cable TV, internet and cell phones. Our expectations have increased and if these things are absent we miss them. I'm not sure it's true to say that I was happier in 1978 without cable or cell phones than I would be now if those things were unavailable. But knowledge of their existence, of the possibilities makes me re-calibrate so that what I called happiness then is at a lower place on the scale I use now.
Why is it at a lower place? Plenty of things one comes to need and require to be happy reduce happiness overall. Crack for example.
This is one of the things about liberalism and enlightenment values, they came in as the merchant and financial class was taking over from the landowners as the dominant power. The conception of what is needed to make people happy is very material as a result. Happiness is the ability to buy lots of products and take out loans.
It's kind of like "the more money you earn, the more money you need." Our needs calibrate to our expectations. So does the happiness scale. If one does not know of the existence of points on the scale above 7, 7 looks like a ten.
Or alternatively materiel plenty has a kind of deflationary effect on human happiness. Every year we need a little bit more than the year before to be happy. It's hardly an appeal to revolutionary change though - "to the barricades lads, that next year we will have thrown off the oppressor and be no happier than we are today!".
So, women are closer to equality with men. But they are not there. Men still make more. In most relationships, the man's career is still the one that drives relocation of the family. Women have gained responsibilities formerly reserved for men (and gladly), but men have not picked up as much of the load of responsibilities that were reserved for women.
You choose some very specific measures there. Why? Women get to spend far more time with their children rather than drudging away at work. Women are the ones who decide how to spend most of the money earned by the household. If being with their children makes women happier and children happier, should we tear them apart so that they can be more "equal"?
One makes the best of the life that is available to them. Suggesting that pre-feminism women were happier is kind of an "ignorance is bliss" assertion. "How ya gonna keep 'em down on the farm
After they've seen Paree'"
If mobile phones have made me less happy than I would have been without them, then what good has eating from that particular tree of knowledge done me? Likewise crack? You hold liberty as an absolute good, even if it makes people unhappy. I don't. Again, was it good that China was opened up to opium so that it's people weren't kept in blissful ignorance of what their lives might be like taking it?
It feels like we have gone around in a big circle. Your ethics are, I think, rooted in liberalism. Hence liberalism becomes ethically self justifying. Whether it makes people happier is irrelevant - it's either assume to be axiomatically true that it makes people happier, or its ignored. My ethics, and I think the ethics of a great many people, are rooted in the long term happiness of people over time.
