Beautifully said, very progressive also!
I am a big fan of the 4-day work week (for the same amount of money as 5 days), it's been transformative for my life. The extra energy and focus you get from that 1 day translates to higher productivity in the 4 days where you do work. Sadly, the current "squeeze em', bleed em' dry, and drop em'" brand of capitalism is incompatible with the majority of the people to experience how good life can be like that.
I certainly ain't looking forward to them raising the retirement age to 1337 by the time I get to retire.
It's like a race where they repeatedly move the finishing line because the organizers took the medals and sold them, while waiting for you to drop dead so they don't have to give you what you are due.
If you, as an employer, want a motivated, energetic workforce who are not slacking off, it's also in your interest to give that opportunity to your employees, as multiple experiments have shown that 4-day work results in increased productivity and employee retention.
today men have the ability to watch kids thanks to formula (though it is better for the kids to eat from mom - this is rarely talked about because it is easy to go too far and starve a baby to death in the exceptions).
There are lot of alternatives. Men can be primary parents (I was, once the kids got to about the age of eight or so, and was an equal parent before that) and they could stay at home (I continued working, but I was already self-employed and working from home, and my ex never worked after having children).
I think the ideal set up (it would have been so for me) would have been for both parents to work part time.
Of course it still comes back to, you should be able to raise a family on the equivalent of one full time income.
Of course, if the leisured society predicted a few decades ago had come to pass it would be one part time salary.
