I agree with you. Growing up, I never heard the end of it. How housework was a full-time job. My mother chanted "men's work is from sun to sun, women's work is never done" like a nursery rhyme, or a prayer. When I moved out, I discovered that working 40 hrs was pretty hard, but housework was a joke. Right now I probably spend around 10-12 hrs per week, max, on housework. And the overwhelming majority of that is just preparing food, which I could spend less time on if I didn't cook. And housework is easy, repetitive, and requires no thought. I mean, I can do laundry unconsciously while writing code in my head.

So since I moved out 22 years ago, my hypothesis has been that people who think housework is a full-time job are actually probably suffering from severe depression and/or anxiety.
