2 part timers should be able to work also

That was also established back before dishwashers, laundry machines, refrigerators (so you can go shopping every couple weeks instead of every day), public school, etc. Modern conveniences streamline a lot of domestic tasks.

I still think a single income should support a family, but maintaining a household isn't as labor intensive as it once was.

Instead of that, we now have unaffordable housing, which forces you into serial tenancies. The rent prices are so high you need to live with one or more people. All of you must work to make the rent. Also there's a deposit, so you must somehow keep on top of the housekeeping, or you will owe money to the landlord. If that sounds unfair and ridiculous, that'll be because it is. But if you complain, you'll be the one that's crazy, because that's just the way the world works

But that doesn't mean the other hours were just leisure time, maintenance of tools, clothing, house, etc also took up quite some time.

And there are hundreds of other necessary activities that aren't listed here. What is your point? The point of the post is that this person (and many others) feel overburdened by the pressures and requirements of modern society. Pointing out that the specific chore of vacuuming doesn't have to happen every day isn't astute.

We're supposed to live communally so you're not the only one doing all this maintaining. You're right, and I share your dream!

Me too comrade. For a brief time in college I was living in a large family home by myself as the owners had relocated to be nearer to good doctors, and it was so crushingly lonely. That is until I invited a D&D group who had lost their place to play into my abode which somehow turned into them all hanging out there at all hours of the day, all weekend, and occasionally overnight during the week. I loved the feeling of the house being so full. Unfortunately, no one had taught them to care for communal spaces and so it became a mess by the time the owners were returning. At the time I didn't have the interpersonal skills to manage that conflict, but I think I'd do better given the chance again.

exactly 10k is bullshit, but I don't see why it still can't be a cutoff. 3-5k is too low, 20k+ only happens when you are actually hiking or sightseeing all day while travelling (unless you have a work where you run back and forth all day)
